and offered Ulcinj to Montenegro as compensation. After the city's annexation to Montenegro, of its 8,000-strong population about 3,000 Albanians left and settled elsewhere in northern Albania. 142 Montenegrin families were brought to settle in the outskirts of Ulcinj in the 1880s. The population of Ulcinj steadily decreased until the post-WWII period. 20th century to present Ulcinj became a part of the Kingdom of Montenegro from 1878 until 1918 when Montenegro was absorbed into the Kingdom of Serbia for a short time before all would be incorporated into the first of the Yugoslav federations at the end of the year. Ulcinj remained within a Montenegrin entity whilst a South Slavic state had existed until 2006 when which it became part of an independent Montenegro following a referendum. During the 20th century, Ulcinj survived heavy declines and new ascents. Ulcinj was the second biggest town of Montenegro when it joined the kingdom in 1880. In just three decades, it backslided to 6th place for economic development and number of inhabitants (after Podgorica, Niksic, Cetinje, Tivar and Plava). During World War I Ulcinj was conquered by Austria-Hungary in 1916 and Italy on November 4, 1918, and since 1920 it was part of the Serbo-Croatian-Slovenian Kingdom, later known as the Kingdom of Yugoslavia.

The Yugoslav Partisans took Ulcinj on November 26, 1944, and the city become part of Socialist Yugoslavia. The 1950s and 1960s marked the greatest period of economic development for Ulcinj, with the construction of a range of modern hotels in the city and the Great Plain, as well as major economic collectives (NHT "Riviera of Ulcinj", "Agroulqini", Primary Building Company, "Otrantkomerc", "Ultep" and others).
