Why is "1969 Malaysian general election" trending?

Wikipedia Overview

General elections were held in Malaysia on Saturday, 10 May 1969, although polling in Sabah and Sarawak was postponed until between 6 June and 4 July 1970. This was the first parliamentary election in Sabah and Sarawak since the formation of Malaysia in 1963. The ruling Alliance Party, consisting of the United Malays National Organisation (UMNO), the Malayan Chinese Association (MCA) and the Malayan Indian Congress (MIC), retained power but with a reduced majority. The Parti Gerakan Rakyat Malaysia (Gerakan) and the Democratic Action Party (DAP), both of which campaigned against the Bumiputra privileges set out in Article 153 of the Constitution which they considered to be a form of institutional racism, made significant gains. Voter turnout was 73.6 percent. The opposition collectively won 54 seats, causing the Alliance to lose its two-thirds parliamentary majority for the first time, a threshold required to pass most constitutional amendments.
