The Aster Revolution was a revolution in Hungary led by socialist count Mihály Károlyi, who founded the Hungarian Democratic Republic.

Károlyi had helped establish the Social Democratic Hungarian National Council (HNC), which demanded the end of the Austro-Hungarian Empire. In the early morning hours of 31 October 1918, with support of the soldiers from the Hungarian Army, HNC protesters wearing the Aster flower helped seize public buildings throughout Budapest. Prime Minister Sándor Wekerle resigned and former Prime Minister István Tisza was murdered.

By the end of the day, King Charles IV had accepted the coup and appointed Károlyi as Hungary's New Prime Minister. The Hungarian Democratic Republic was proclaimed on 16 November 1918 with Károlyi named as president.

In March 1919, the republic was overturned by another revolution, and the Hungarian Soviet Republic was created. It had a short life, followed by the restoration of the Kingdom of Hungary, but as an independent nation.

Aster Yohannes is the wife of detained Eritrean politician Petros Solomon. She is a veteran of Eritrean People's Liberation Front (EPLF).

She has been in prison held in an undisclosed place by the Eritrean government since December 2003. She was detained by security personnel at Asmara International Airport in the capital Asmara on 11 December 2003, when she returned after a three year period study at the University of Phoenix in Arizona, USA. She had returned to Eritrea with a newly issued Eritrean passport, to be with her four children aged between 6 and 13 at the time of her arrest. During her absence her children had been cared for by her mother.

Prior to her departure to Eritrea from the US, she was reportedly given assurances of safety by the then Eritrean Ambassador to the United States Girma Asmerom The Eritrean authorities have given no reason for her arrest or said where she is held. She has not been permitted to see her family. Amnesty International fears she could be subjected to torture or ill-treatment, held in secret and detained for an indefinite period without charge or trial.
