Most Super Bowl Wins

While many a football aficionado knows the Pittsburgh Steelers were the reigning champs of the Super Bowl, in recent years the New England Patriots have emerged as worthy opponents. Both the Steelers and the Patriots deserve recognition for being the only two teams in NFL history with six Super Bowl wins. The Steelers have appeared in the Super Bowl eight times giving them a 75% winning percentage. The Patriots, on the other hand, have appeared eleven times, so they have a 54.5% winning rate. However, there are still many more teams with Super Bowl wins to keep in mind throughout this season.

Team	City	State	Appearances	Wins	Winning %	Season(s) appeared	Season(s) won
Pittsburgh Steelers	Pittsburgh	PA	8	6	0.75	1974, 1975, 1978, 1979, 1995, 2005, 2008, 2010	1974, 1975, 1978, 1979, 2005, 2008
New England Patriots	Boston	MA	11	6	0.545	1985, 1996, 2001, 2003, 2004, 2007, 2011, 2014, 2016, 2017, 2018	2001, 2003, 2004, 2014, 2016, 2018
San Francisco 49ers	San Francisco	CA	6	5	0.833	1981, 1984, 1988, 1989, 1994, 2012	1981, 1984, 1988, 1989, 1994
Dallas Cowboys	Dallas	TX	8	5	0.625	1970, 1971, 1975, 1977, 1978, 1992, 1993, 1995	1971, 1977, 1992, 1993, 1995
Green Bay Packers	Green Bay	WI	5	4	0.8	1966, 1967, 1996, 1997, 2010	1966, 1967, 1996, 2010
New York Giants	East Rutherford	NJ	5	4	0.8	1986, 1990, 2000, 2007, 2011	1986, 1990, 2007, 2011
Oakland Raiders	Oakland	CA	5	3	0.6	1967, 1976, 1980, 1983, 2002	1976, 1980, 1983
Washington Redskins	Washington	D.C.	5	3	0.6	1972, 1982, 1983, 1987, 1991	1982, 1987, 1991
Denver Broncos	Denver	CO	8	3	0.375	1977, 1986, 1987, 1989, 1997, 1998, 2013, 2015	1997, 1998, 2015
Baltimore Ravens	Baltimore	MD	2	2	1	2000, 2012	2000, 2012

Aside from the Steelers and Patriots competing for the most Super Bowl wins in the NFL, the Dallas Cowboys and San Francisco 49ers are tied with five Super Bowl wins. The Cowboys have actually played the top winning team, the Steelers, in three different Super Bowls. The Steelers won Super Bowls X and XIII and the Cowboys beat the Steelers in Super Bowl XXX. Talk about a long-standing rivalry!

The Patriots have also gone head to head more than once with the New York Giants. These two teams have played each other twice in the Super Bowl and surprisingly enough, the Giants beat the Patriots in both Super Bowl XLII and XLVI.

The Washington Redskins and their three Super Bowl wins haven’t appeared again since they won the Super Bowl way back in 1991. That’s a pretty long Super Bowl drought for a three-time champion team.

There are also ten other NFL teams that have won at least one Super Bowl.

Highest Winning Percentage

The more times a team has appeared in the Super Bowl, the harder it is to maintain that perfect winning percentage. Only four teams in the entire league can say they have a perfect winning percentage.

Team	Appearances	Wins
Baltimore Ravens	2	2
New Orleans Saints	1	1
New York Jets	1	1
Tampa Bay Buccaneers	1	1

These four teams have won just as often as they have appeared in the Super Bowl: the New Orleans Saints (in 2009), the Tampa Bay Buccaneers (in 2002), the New York Jets (way back in 1968), and the Baltimore Ravens (both in 2000 and then again twelve years later in 2012). The Jets have had a substantial Super Bowl drought, not having won nor appeared in a Super Bowl since their win in Super Bowl III.

AFC vs. NFC

The National Football League (NFL) is comprised of the American Football Conference (AFC) and the National Football Conference (NFC), and these two conferences have a rivalry all their own. With 16 teams in each conference and a grand total of 32 teams in the NFL, there is some steep competition in order to end up one of the two teams that get the chance to play in the Super Bowl each year.

The NFC has more Super Bowl wins than the AFC. With 27 wins, the NFC has just a small leg up above the AFC which has 26 Super Bowl wins. Most of the NFC’s 24 wins come from the 1980s and 1990s. The NFC won 16 out of 20 Super Bowls during the two decades. They even went on a 13-year winning streak from Super Bowl XIX to Super Bowl XXXI.

However, the AFC made a great comeback with two consecutive wins in 1997 and 1998. The AFC would go on to win 9 out of the 12 Super Bowls leading from 1997-2008.

Currently, the NFC and the AFC are pretty even, with five teams from the AFC and five from the NFC winning Super Bowls on and off since 2010.

NFL Teams Without a Super Bowl

Although the focus of this post is on winning, we thought it would be neat to provide a list of the twelve NFL teams that have not won a Super Bowl title. This leaves more teams (20/32) with a Super Bowl win than those who have never seen that coveted ring.

• Buffalo Bills (appeared in 1990, 1991, 1992, and 1993)
• Minnesota Vikings (1969, 1973, 1974, and 1976)
• Atlanta Falcons (1998, 2016)
• Cincinnati Bengals (1981, 1988)
• Carolina Panthers (2003, 2015)
• Arizona Cardinals (2008)
• Los Angeles Chargers (1994)
• Tennessee Titans (1999)
• Cleveland Browns (never appeared)
• Detroit Lions (never appeared)
• Jacksonville Jaguars (never appeared)
• Houston Texans (never appeared)

Just a few years ago, the Philadelphia Eagles would have been included in this list. But the Eagles won the Super Bowl for the first time ever in 2017.

Highest Scoring Super Bowls

As for the highest-scoring Super Bowls, the 1989 game saw the highest score for one team. In this Super Bowl XXIV, the San Francisco 49ers played a sweeping game against the Denver Broncos that resulted in a 55-10 win for the 49ers, and the Super Bowl record for most points scored by one team.

A close second came three years later with Super Bowl XXVII. In this game, the Dallas Cowboys beat the Buffalo Bills 52-17 in the second-highest points scored by a single team Super Bowl game in history.

The highest cumulative game score goes to Super Bowl XXIX two years later with a San Francisco 49ers vs. San Diego Chargers game that ended in a 49-26 win for the 49ers. The cumulative points for both teams add up to 75.

Curious to see if the upcoming Super Bowl surpasses any of these records? If the New England Patriots win this year, they will beat the Steelers for the most wins. Watch the game on the first Sunday of February to find out.

Another decade has come and gone. So that history doesn’t repeat itself, let’s remember the 164 major events that happened exactly a century ago in 1920. It was a year of major healthcare milestones like the creation of hydrocodone. 1920 also saw several U.S. political events (women’s suffrage) that changed the history of the country forever. While 1920 was full of health and political advancements, deadly disasters also wreaked havoc throughout the year. These natural and man-made disasters included the Haiyuan earthquake, which caused a landslide that killed 180,000 people in China as well as 39 wars, revolutions, and uprisings, like Ireland’s Bloody Sunday.

View 1920 Events in a full screen map

Use the map above to browse 1920’s events as sorted into categories such as Wars, Revolutions, and Uprisings (find the data here). Then, learn more about each category of events, like how the very first event to kick off 1920 was related to war.

Wars, Revolutions, and Uprisings

In 1920 there were wars, revolutions, and uprisings aplenty. These included the Polish-Soviet and the Polish-Lithuanian Wars along with the Irish War of Independence and many others as displayed on the map.

The Polish-Soviet War and the Polish-Lithuanian War

The Polish and the Soviets had been fighting a war since February 1919 — of which the Russian Revolution was a cause; read more about it here — but 1920 was the year the war ended. However, several important events occurred prior to the war’s conclusion, including the very first event to kick off 1920: when the Russian Red Army increased its troops along the Polish border from four divisions to 20 in January. After this, the next major event of the Polish-Soviet War occurred on April 24th when Polish and anti-Soviet Ukrainian troops attacked Russia’s Red Army in Soviet Ukraine. Throughout the summer months of 1920, Polish and Russian troops went back and forth in Kiev. On May 7th, Polish troops occupied Kiev, but later in the summer, the Russian Red Army took it back. On July 22nd, Poland sued for peace, but Russia rebuked them. Then came the Battle of Warsaw: on August 13th, Poland defeated the Russian Red Army. Russia sued for peace with Poland later in the fall, but the war didn’t end until October 16th when the Polish army captured Tarnopol, Dubno, Minsk, and Dryssa.

Yet, Soviet Russia wasn’t the only country Poland was at war with during 1920. Poland was also engaged in a war with Lithuania. However, just one major event took place in 1920, when, on October 9th, Polish troops took Vilnius. This was just days before they took the four cities from Soviet Russia. Clearly, Europe was quite busy in 1920. In fact, more major events occurred throughout the continent than anywhere else that year. Most of Europe’s 1920 events were wars, revolutions, and uprisings, to which Ireland contributed as they fought the Irish War of Independence.

Irish War of Independence

The Irish War of Independence lasted from 1919 to 1921, and 1920 was full of monumental events. In late March, British recruits to the Royal Irish Constabulary arrived in Ireland. The Belfast riots on August 3rd were a response to British presence. Ten days after the riots, the U.K.’s Parliament passed the Restoration of Order in Ireland Act, which would try members and supporters of the Irish Republican Army by court-martial instead of by jury in criminal court.

Things cooled off until November 21st, deemed “Bloody Sunday,” when the Irish Republican Army shot and killed 14 British undercover agents in their homes in Dublin. Later the same day, the Royal Irish Constabulary opened fire on a crowd at a football match, killing 13 spectators and one player, and also wounding 60. Later that same night, three men were shot in Dublin Castle.

Two more events of the Irish War of Independence happened post-Bloody Sunday: the Kilmichael Ambush and declaration of martial law. But Europe wasn’t the only continent in the midst of conflict throughout the year. Other notable wars, revolutions, and uprisings of 1920 include the Mexican Revolution, Russian Civil War, Estonian War of Independence, 1920 Palestine riots, Greek Summer Offensive, Battle of Maysalun, Second Silesian Uprising, Bukhara operation, and the Carinthian Plebiscite.

Sports

Did you know that the NFL was established in 1920? Yes indeed, on September 17th, 1920, America’s favorite Sunday pastime was created. For more fun football facts, see maps on where college football players come from, NCAA football champions mapped, and American football hall of famers not all born in Texas. For more major sports-related events of 1920, including pro-wrestling, the Olympics, baseball, and horse and dog racing, keep reading.

1920 saw a lot of firsts in sports: the oldest existing movie of pro-wrestling was filmed (Joe Stetcher vs. Earl Caddock), the first dog racing track to employ an imitation rabbit opened, the first Prix de l’Arc de Triomphe horse race occurred in Paris, and the Olympic symbol (five interlocking rings) and flag were displayed for the very first time at the Summer Olympics in Belgium. The first game of the Negro National baseball League was also played in Indiana.

Health and Disasters

Health-wise, noteworthy events of 1920 include a woman who attempted suicide in Berlin and later claimed she was Anastasia, the Grand Duchess of Russia. This was not the first nor the last time someone impersonated the Grand Duchess, and it later inspired the 1997 children’s movie, Anastasia. Plus, France outlawed birth control in 1920 and pain-relieving opioid hydrocodone was synthesized in Germany for the first time that same year. The HIV pandemic also likely originated in Léopoldville (modern-day Kinshasa), the capital of the Belgian Congo at this time.

As for disasters, 1920 was hit with two major earthquakes: the Gori and the Haiyuan. The Gori earthquake hit Gori (Democratic Republic of Georgia), killing 114 and the Haiyuan earthquake caused a landslide in Gansu Province, China, killing 180,000. Other natural disasters included the Louth, Lincolnshire, England floods which killed 23 people.

Then there were the U.S.-specific disasters: the 1920 Palm Sunday tornado outbreak, which hit the U.S.’s Great Lakes and Deep South and the Wall Street bombing. The Wall Street bombing saw a bomb placed in a horse wagon that exploded in front of the J. P. Morgan building in New York City. The bomb killed 38 and injured 400. There were many other major 1920 events in the U.S., most related to culture and politics.

American Culture and Politics

In America, 1920 was the year that two Amendments to the Constitution passed: the Eighteenth Amendment (Prohibition) and the Nineteenth Amendment (women’s suffrage). Additionally, the 1920 presidential election where Warren G. Harding (R) defeated James M. Cox (D) was the first national election where women could vote.

Other than when the U.S. Post Office ruled children may not be sent via parcel post (because apparently, 1920’s Americans were doing that), the rest of the notable cultural and political events involved radios. In August, Detroit began the first commercial radio station and in September, the first domestic radio sets became available in stores for $10 (about $180 adjusted for inflation).

Ahead of any presidential election, there are events Democratic and Republican voters alike need to know. These include conventions, caucuses, debates, and other categories of events that occur leading up to a presidential election. If you don’t have time to track each of the 90+ presidential primary events for 2020, you can get by as long as you keep an eye out for key dates like Super Tuesday and the additional presidential primary events that play a huge role in the election of the next U.S. president in 2020.

The map above has all the 2020 presidential primary events you need to know, which we got from the New York Times’ 2020 Presidential Election Calendar. Sort the map by presidential primary event categories or the year and month of the event to narrow down the dates you need to know most.

Conventions, Caucuses, and Other Categories

We are tracking 91 presidential primary events for the 2020 election. That’s a lot to remember! Luckily, we can break down the events into five categories: conventions, debates, the election, and primaries and caucuses. Let’s learn what events from each category entail.

Conventions

On the map above are two nominating conventions, which you may recognize from the presidential nominating convention locations since 1832. These conventions are where the two major political parties will officially select their candidate for President of the United States. The Democratic National Convention takes place July 13-16, 2020, in Milwaukie, Wisconsin, while the Republican National Convention starts August 24th, 2020 and runs through the 27th in Charlotte, North Carolina.

Debates

Twelve primary debates are scheduled throughout the 2020 presidential election cycle, all of which are for the Dems to debate amongst themselves. Six of these Democratic primary debates take place in 2019 while six more are scheduled for 2020 as Democrats narrow down their presidential candidate.

Republicans are skipping their own primary debates this election as primary debates are for candidates of the same political party. Seeing as incumbent Presidents have a better chance at winning the presidential election than any new candidate of the same political party, Republicans are pretty much guaranteed to stick with Donald Trump and they don’t need to hear from any other GOP candidates to make that decision.

There are also three presidential debates for when each party nominates their #1 candidate at the nominating conventions, along with one vice presidential debate.

The Election

The election is a category with just one event: the 2020 presidential election. This cycle, the election will take place on Tuesday, November 3rd, which is quite early. Election day is always on the Tuesday after the first Monday of November, with the earliest possible date being November 2nd and the latest possible date being November 8th.

Primaries & Caucuses

While these two categories accomplish the same goal of selecting a primary candidate, primaries and caucuses use different methods to do so. A primary is similar to a general election in that it is a statewide voting process where voters cast ballots for the primary candidate of their choice. A caucus, on the other hand, is comprised of local gatherings where voters decide which primary candidate to support and select delegates for the nominating conventions.

The 2020 presidential primary season has seen the cancelation of several of the primaries and caucuses that usually take place: the Kansas Republican caucuses, Nevada Republican caucuses, the Arizona Republican primary, and the South Carolina Republican primary. All of the canceled events were meant to be for Republicans to select their candidate. However, just like the absence of GOP primary debates, Republicans in these states already know they’ll be supporting their incumbent. It turns out canceling primaries and caucuses is quite a common practice. Throughout the 2012 election when Barack Obama was the incumbent, several of these same states canceled their Democratic primaries and caucuses in support of the incumbent at the time.

Keep an Eye out for Key Dates Like Super Tuesday

Even with the 91 presidential primary events broken down into categories, the events are still not the easiest to track. Short from making our map your browser’s homepage, just keep an eye out for the one month or even just the one key day during which most of the presidential primary events take place.

There are 39 primary events scheduled for March 2020, which is nearly 48% of all primary events for this election. These March events include the primaries of key states like Michigan and Ohio which will provide insight into the preferences of suburbanites, African-Americans, and the white working-class. Then there is the Super Tuesday in March, which accounts for nearly 40% of delegate allocation. Political analysts expect the presidential primary race to be decided on Super Tuesday (March 3rd, 2020), when all of the following primary events all take place:

• American Samoa Democratic caucus
• Alaska Republican conventions
• Texas primaries
• Alabama primaries
• Arkansas primaries
• Colorado primaries
• Maine primaries
• Massachusetts primaries
• Minnesota primaries
• North Carolina primaries
• Oklahoma primaries
• Tennessee primaries
• Utah primaries
• Vermont primaries
• Virginia primaries
• Democrats Abroad primary
• California primaries

Most notable on Super Tuesday are the California and Texas primaries. As California has the most delegates in the U.S., it is one to keep an eye out for on Super Tuesday. Texas has the second-largest amount of delegates, so it too is one to watch on this monumental March day.

More Presidential Primary Events That Play a Huge Role

In addition to Super Tuesday, what other 2020 presidential primary events play a huge role in determining the presidential candidates? The Iowa caucus is where the first primary votes will be cast. These first votes can impact who the choices of voters later on, so pay attention to the results of the Iowa caucus on Monday, February 3rd. The next event to watch, the New Hampshire primary, takes place on Tuesday, February 11th.

Following the New Hampshire primary on the 11th is Nevada’s Democratic caucus on Saturday, February 22nd. This caucus is known for being well-attended and it is also the first state caucus with a large Latinx population. The results of Nevada is a good indication of how other voters are leaning. Then, on Saturday, February 29th, the spotlight is on South Carolina. Their Democratic primary is a good predictor of who black voters will select.

The last presidential primary event that will play a huge role is the New York primary, which is scheduled for Tuesday, April 28th. If any Democratic primary candidate is ahead at this point, the leaders of the Democratic party will likely call the primary race on this day.
