Ukrainian Unity Day (Den' Sobornosti) is celebrated on January 22 every year. Unity Day is a Ukrainian observance that commemorates the Treaty of Unity signed on January 22, 1919. This year we celebrate the 98-th anniversary of this event when eastern and western Ukraine was united through the Treaty of Unity.
Historically, up until 1919, these territories – Ukraine's People Republic and West Ukrainian People Republic – belonged to different empires. The agreement was aimed at creating a unified Ukrainian state, a movement long awaited by the intelligentsia on both sides. «The territory of Ukraine, divided over the centuries, including Galicia, Bukovyna, Carpathian Ruthenia, and Dnieper Ukraine will now become a great-united Ukraine. Dreams, for which the best sons of Ukraine fought and died for, have come true», - was written in the text of the universal made by the Directorate of the Ukrainian People's Republic.
To mark the 71st anniversary of the signing of the Act Zluky in 1990, over 300,000 Ukrainians created a human chain (approx. 482 km) from Ukrainian capital Kiev to the western Ukrainian city of Lviv on January 21, 1990. Also, for the first time since the period of the Ukrainian People's Republic, the blue and yellow national flag was raised.
On January 21, 1999, the President of Ukraine decreed the "Day of Reunion of Ukraine" (Den’ Sobornosti Ukrainy), a government holiday, celebrated every year on January 22 to mark the political and historical significance of the 1919 agreement.
