jan 2, 1982 - Sometime in 1982: Citizenship Law
The government of Myanmar passed a citizenship law saying that Rohingya could apply if they spoke an officially recognized language and could prove their families had lived in the country before independence. But most Rohingya were never granted the paperwork to prove their roots. They did not make the list of the 135 recognized ethnicities in Myanmar.
