Ljig is a relatively new settlement which originated at the beginning of the 20th century. 1911 was the first time Ljig was mentioned in history books when the construction of the railway Lajkovac – Gornji Milanovac began. In 1917 a beautiful railway station Babajic – Ljig was constructed in the heart of today’s Ljig. A primary school was built in 1907. The remains of the “Vavedenje” monastery in Slavkovica tell the story of a turbulent past and impressive life in the 11th century. It is assumed that Despot Djurdje and Stefan Brankovic, two Serbian rulers from that period, were sarcophaguses. According to a legend it is where Jerina, the despot’s wife, is buried.

In 1917 on the territory of today’s Municipality of Ljig a well known battle occurred, the Battle of Kolubara. This battle is documented in Serbian history books and books of all significant military academies in the world. The monument known as “1 300 Corporals” on Mount Rajac and others serve as a reminder of this.

Between the two world wars Ljig together with Lipovica, Boblija, Petakovac and Vrgnjic made up the Municipality of Gukos. In 1922 Ljig separated and became a town in its own right. Not long after that Ljig became entitled to organizing markets and public entertainment. In 1928 a Worker’s School was owned, while in 1930 a Health Union was formed as well as a church. Prior to this residents had to go to the Moravci church which was built on the foundations of the homes of Hadzi Ruvim and Hadzi Djera.
