The document discusses the history of Brexit, beginning with the etymology of the term and the UK's initial attempts to join the European Union in the 1960s. It then covers important political events between the 1970-1990 period, including UK uncertainty over EU membership and Margaret Thatcher's resignation. Referendums in 1974 and 2016 are discussed, with the latter resulting in a vote to withdraw the UK from the EU. The negotiations and withdrawal process as governed by Article 50 are outlined.
