<P0-S0> The 1957 National Football League championship game was the 25th annual championship game, held on December 29 at Briggs Stadium in Detroit, Michigan. <SEP> <P1-S0> He rose from a modest beginning in Acadia in 1683 as an explorer, trapper, and a trader of alcohol and furs, and he achieved various positions of political importance in the colony. <P1-S1> He was the commander of Fort de Buade in St. Ignace, Michigan in 1694. <P1-S2> In 1701, he founded Fort Pontchartrain du Détroit which became the city of Detroit, which he commanded until 1710. <P1-S3> Between 1710 and 1716, he was the governor of Louisiana, although he did not arrive in that territory until 1713. <P1-S4> Antoine Laumet de la Mothe, sieur de Cadillac (/ ˈkædɪlæk /, French: (kadijak); March 5, 1658 -- October 16, 1730), usually referred to as Antoine de la Mothe Cadillac (also spelled Motte), was a French explorer and adventurer in New France which stretched from Eastern Canada to Louisiana on the Gulf of Mexico. <SEP> <P2-S0> The Lions moved to the newly constructed Silverdome and have played their home games indoors ever since (at Ford Field since 2002). <P2-S1> On Thanksgiving Day, November 28, 1974, after over 35 years, the Lions played their final game in Tiger Stadium, where they lost to the Denver Broncos 31 -- 27 in front of 51,157, amidst snow flurries and a 21 - point Broncos 3rd quarter. <SEP> <P3-S0> the largest crowd to ever gather at the silverdome was on september 18, 1987 for mass with pope john paul ii, with a reported attendance of 93,682 -- just shading the record of 93,173 set at the silverdome on march 29, 1987 for wrestlemania iii. <P3-S1> another notable audience attendance record had earlier been broken on april 30, 1977, when the english rock band led zeppelin played in front of 76,229 fans at the silverdome. <P3-S2> this was, at the time, a new world record attendance for a solo indoor attraction, beating the 75,962 that the who attracted there on december 6, 1975. the detroit pistons also set numerous nba attendance records during their time at the silverdome; regular season, 61,983 vs. boston, january 29, 1988; playoffs, 41,732, vs. l.a. lakers, june 16, 1988. <SEP> <P4-S0> however, the club was still struggling off - field. <P4-S1> one of the bears' biggest problems was its lack of support (both on and off the field) in melbourne, the location of most of its away matches. <P4-S2> in mid-1996, the struggling fitzroy football club collapsed due to financial pressures and was seeking to merge its assets with another club. <P4-S3> when a merger with north melbourne in forming the north fitzroy kangaroos failed to win the support of the other afl clubs, a deal for a merger was done between fitzroy and the bears. <P4-S4> the new team was known as the brisbane lions, based at the gabba, with northey as the coach of the merged club. <P4-S5> as such, the history of the brisbane bears as an individual entity ended after the 1996 season, with ten seasons of competition and the third - place finish in 1996 as its best performance. <P4-S6> the bears last match as a separate entity was a preliminary final on saturday 21 september 1996 at the melbourne cricket ground (where the bears played their first vfl / afl game). <P4-S7> it was against north melbourne, their first and last ever opponents, the bears lost by 38 points to north who would go on to win the premiership that year. <P4-S8> when the team came off the mcg, the bears were finished after a short and troubled existence.
