Why is "1970s in Bangladesh" trending?

Wikipedia Overview

The 1970s was a decade of the Gregorian calendar that began on 1 January 1970, and ended on 31 December 1979. It was a very significant decade in the history of Bangladesh, because this is the decade in which Bangladesh emerged as a sovereign state. The decade began with a devastating cyclone that ravaged the southern part of the country. The next year the country went into Liberation war and achieved independence from Pakistan. The government of Sheikh Mujibur Rahman administered the newly formed country between 1972–1975, but their rule soon came to an end through a series of coups and counter coups in the later part of the decade. Economically the country struggled because of the war (1971) and famine (1974) throughout the decade and was highly dependent on foreign aids. Culturally, in this decade Bangladesh started to establish its own identity as an independent nation.
