>Oakmont pride campaign starts with bonfire
The fire rises. This ties in well with Bane's post-credit scene tactics of pretending to be a populist figure trying to gain power "and give it to you, the people." Of course he was only pretending to do this, and in reality was The League of Shadows, trying to destroy Gotham (filmed in Philadelphia) for its decadence, as seen with the "pride campaign." This also ties in with the then-recent developments in the Occupy Wall Street movement, on which Bane's theatrics were based. The real life OWS movement was recently destroyed by the injection of identity politics (again symbolized by the pride campaign), which were used to subvert the economic focus of the movement. The first scene of the film establishes that Bane and his men started the fire, and when we later see that the pride campaign started with the fire, we can infer that Bane is actually only pretending to be interested in the economic motives that he claims to care about, and in reality is using those supporters for his own ends.
The pride campaign bonfire being in 1990 also makes sense, because in Nolan's previous film Batman Begins, which focused on the Bateman character and also featured Bane (going by his alternate name "The League of Shadows" and played by Liam Neeson instead of Tom Hardy), we learn that The League of Shadows was in the process of trying to destroy Gotham through subtle manipulation when Bateman was a young boy. So we were previously told that The Fire was around in the late '80s/early '90s, and again they were using identity politics to destroy the city.
