Today is the 20th anniversary of the election of the first democratic non-Communist Government in Poland after WW II, the event which presaged the later changes throughout Eastern Europe and the USSR of that revolutionary year.
Today is also the 20th anniversary of the brutal and unprovoked massacre of the student protesters in Tiananmen Square, Beijing, by the PLA, under the illegal orders of Deng Xiaopeng and his henchmen.  Only the brave Zhao Zhiyang, then General Secretary of the Communist Party of China, and Hu Qili, then a Politburo Standing Committee member, argued against Deng’s decision to impose martial law within the ruling party internal discussions.
This post honours the heroes who died or were imprisoned in that period.   Previous posts in this series are here.
