The Disruption in Edinburgh of the Free Church of Scotland from the Church of Scotland.

The Disruption of 1843, also known as the Great Disruption, was a schism in 1843 in which 450 evangelical ministers broke away from the Church of Scotland to form the Free Church of Scotland. The main conflict was over whether the Church of Scotland or the British Government had the power to control clerical positions and benefits. The Disruption came at the end of a bitter conflict within the Church of Scotland, and had major effects in the church and upon Scottish civic life.

Edinburgh is the capital city of Scotland and one of its 32 council areas. It is located in southeast Scotland and is bounded to the north by the Firth of Forth and to the south by the Pentland Hills. Edinburgh had a population of 506,520 in 2020, making it the second-most-populous city in Scotland and the seventh-most-populous in the United Kingdom. The wider metropolitan area had a population of 912,490 in the same year.

The Free Church of Scotland is a Scottish denomination which was formed in 1843 by a large withdrawal from the established Church of Scotland in a schism known as the Disruption of 1843. In 1900, the vast majority of the Free Church of Scotland joined with the United Presbyterian Church of Scotland to form the United Free Church of Scotland. In 1904, the House of Lords judged that the constitutional minority that did not enter the 1900 union were entitled to the whole of the church's patrimony ; the residual Free Church of Scotland acquiesced in the division of those assets, between itself and those who had entered the union, by a Royal Commission in 1905. Despite the late founding date, the leadership held a doctrine of unbroken succession of leaders going back to the Apostles.

The Church of Scotland is a Presbyterian denomination of Christianity that holds the status of the national church in Scotland. It is one of the country's largest, having 245,000 members in 2024 and 259,200 members in 2023. While membership in the church has declined significantly in recent decades, the government Scottish Household Survey concluded that 20% of the Scottish population, or over one million people, identified the Church of Scotland as their religious identity in 2019.
