An entrepreneurial American cowboy named Guy Weadick visited Calgary and the surrounding area in the early 1900s and envisioned a tribute show to the pioneers of the west and a cowboy championship contest. He arranged $100,000 in financing from the "Big 4" (influential ranchers and businessmen George Lane, Archie McLean, Patrick Burns and A.E.Cross) and in September 1912, the first Calgary Stampede came to life.
- Calgary was established when Fort Calgary was built by the North West Mounted Police at the confluence of the Bow and Elbow rivers.
- The First Nations of southern Alberta signed Treaty 7 near Gleichen in September. The Siksika, Kainai, Piikani, Tsuu T’ina and Nakoda peoples would become an integral part of the Calgary Stampede’s Parade, downtown attractions and Indian Village.
- The Canadian Pacific Railway arrived at Calgary, later bringing visitors from as far east as Winnipeg to attend the first Stampede.
- The Calgary Agricultural Society was formed on August 16. With a population of about 500 people, Calgary was incorporated as a town on November 7.
- The Agricultural Society was reorganized after interruption by the 1885 Riel Rebellion. The first exhibition/fair was held October 9. Calgary’s population was about 2,000 people.
- With the help of Major James Walker, the Agricultural Society acquired 94 acres of land from the Dominion of Canada and began improvements to the site with a race track, cattle sheds and an exhibition building. This land on the Elbow River continues to be the site of Calgary Stampede.
- Calgary became a city with a population of 3,900.
- Land owned by the Agricultural Society reverted to the City of Calgary, when the city paid a deficit of $7,000. The Calgary Agricultural Society was reorganized as the Inter-Western Pacific Exposition Co. in March.
- The first Calgary bull sale was held on April 12. Sixty lots of cattle were sold with entries including various breeds of bulls, cows and heifers. The world-renowned bull sale continues to this day.
- Guy Weadick, of Rochester, New York, visited Calgary for the first time serving as the agent for rodeo entertainer Will Pickett. He also met his future wife Florence LaDue in Chicago.
