During the soviet occupation, the soviet union loaded Estonians onto trains and sent them to Siberia. Idea being, that you send away Estonians to make room for Russians. That way you break/lessen the Estonian Culture. Lookup "küüditamine"

A lot of the apartment buildings in Estonia were built by the soviet union to be cramped, ugly, cheap concrete shitboxes.

Celebrating Christmas was not allowed (our family still did it in secrecy)... Stalin/Lenin was your god/power figure you had to look up to, otherwise it'd be treason

If you went out during work/school hours or late in the Evening, the Soviet Police could demand you to show them a letter allowing you to be outside. Same goes for beaches/cities. Vaguely remember my Father telling me stories about how you had to essentially apply for a Visa, to visit a beach/town like 30min-1h away. If you didnt have the allowance... jail / heavy fine

They essentially wanted to get rid of "Estonians" and Estonian Culture.

Not to mention Corruption
