The city of Sofia is the second oldest in Europe, with humans inhabiting it since at least 8 BC, but it is believed that the area has been inhabited for at least 30,000 years. In the 1870s, the city was liberated from the rule of the Ottomans. By the end of the decade, the city was named as the capital. During this time, the population exceeded 11,000.
In the years that followed, the city’s population continued to grow as migrants made their way into the area. In the early 1900s, Sofia was involved in multiple wars. This included the Second Balkan War, and World War II. During World War II, bombings from the US and the UK destroyed thousands of buildings and killed thousands of people. The city was invaded in 1944 by the Soviet Red Army. The next year, Fatherland Front took control.
In the years that followed, Bulgaria became the People’s Republic of Bulgaria, before changing again in 1990 to the Republic of Bulgaria. The city has continued to see growth, both in terms of dwellings and buildings and its population, which has risen because of migration from rural areas.
The population of Sofia has grown significantly since the census was first taken in the 1870s. The city through each census has recorded growth. Because of the high rate of immigration to the capital city, these numbers are only expected to continue to grow in the years ahead.
