A year has past since the student demonstrations in Maidan square.
Ukrainians came to commemorate those who lost their lives when the protests turned into a revolution which brought in a pro-Western government.
President Poroshenko, who continues to face an uprising in the east from pro-Russian separatists, also came to pay his respects.
Despite a truce in the east, violence rages on. The UN reported that during the two-month long ceasefire alone, almost 1,000 people have lost their lives.
Some in the crowd shouted down Poroshenko for failing to make national heroes of those killed during the protesters.
Earlier on, five parties agreed to form a coalition signing an deal which included a thorough investigation of the killings.
