The Founders' Day Celebration is a yearly event in Mystic Falls. In 2010, the town celebrated the event's 150th anniversary. The town itself (Mystic Falls) was founded in 1860. Preparations for the celebration begin a few months in advance.
Throughout The Vampire Diaries Series
In Founder's Day, the town held the first Founders' Day celebrations of the series. The celebrations included a marching band and a large float. The large float was compromised of the Timberwolves football team, a reconstruction of the Battle of Willow Creek and Miss Mystic Falls and her court (Elena and Caroline, with escorts Stefan and Matt).
During the celebration, the device was activated after the Founders' Council got wind of a rumour that the tomb vampires were planning on killing the Founding Families in retribution for their ancestors trapping them in the church for 145 years. Once the vampires (and werewolves) were incapacitated by the device, the Sheriff's deputies injected the vampires with vervain while the townspeople were setting off fireworks. Unfortunately, Mayor Lockwood, who, unbeknownst to him or his immediate family, was an untriggered werewolf, was also affected by the device and ultimately died after a vervained vampire killed him in the basement of the Gilbert medical clinic.
This event also took place in the novels, specifically The Struggle. In the novel, Caroline wanted to publicly read Elena's diary to have Stefan arrested and to humiliate Elena. Elena was chosen to be "Soul of Fell's Church."
