The Conservative Party of British Columbia (BC) has a long and complex history, with various mergers, splits, and name changes over the years. Here is a brief overview:

The party's origins can be traced back to the 1903 provincial election, when the "Conservative Association" won a majority of seats in the BC Legislature. In the early years, the party competed with the Liberals for political dominance in the province.

In 1907, the party officially changed its name to the "British Columbia Conservative Party." The party remained in power until 1916, when it was defeated by the Liberals.

In the 1920s and 1930s, the Conservative Party experienced internal divisions and struggled to compete with the Liberals and the newly formed Co-operative Commonwealth Federation (CCF, later the NDP) in BC's political landscape. In 1941, the party merged with the BC section of the federal Conservative Party to form the BC Progressive Conservative Party.

The BC Progressive Conservatives were a separate entity from the federal Progressive Conservative Party of Canada, and they competed in BC provincial elections from 1941 to 1952. During this period, the party won two elections (1945 and 1949) under the leadership of Premier W.A.C. Bennett.

The Social Credit Party first won power in British Columbia in the 1952 provincial election, defeating the incumbent Liberal government. W.A.C. Bennett became premier and led the Social Credit government until 1972, when he retired.

Meanwhile, the Conservative Party of British Columbia continued to exist as a separate party, competing with the Social Credit Party and other political groups. In 1965, the Conservative Party merged with a small right-wing party called the BC Progressive Party to form the "British Columbia Progressive Conservative Party". This new party competed in provincial elections from 1966 to 1986, but did not win any elections during that time.

The Conservative Party of British Columbia continued to exist as a separate party after the BC Liberal Party was formed in 1986. In fact, the Conservative Party of BC was one of the parties that merged to form the BC Reform Party in 1989, which later became the BC Conservative Party in 1991.

The BC Conservative Party ran candidates in provincial elections throughout the 1990s and 2000s, but it was not able to win any seats in the legislature. In 2013, the party merged with the British Columbia First Party to form the BC Conservative and Unionist Party, which also failed to win any seats in the subsequent election.

Despite the existence of the BC Conservative Party and its various incarnations, the BC Liberal Party has been the dominant centre-right party in British Columbia politics for several decades. It has won the most seats in every election since 1991, forming government in all but one of those elections.
