It is located in the western part of the country, sharing 425 km of border with Iraq, and also bordering on the provinces of Kermanshah, Lorestan, and Khuzestan. The largest city and also the provincial capital is the city of Ilam with a population 194,030. As of 2016 census, the population of the province was 580,158 people and is the least populated province in Iran. Majority of the population, about 80%, speak dialects of Kurdish, 10% speak Luri and 6% Laki.
  Since 1937, Ilam was a part of the Kermanshah province. In 1974, parts of Lorestan and Khuzestan were added to Ilam governorate-general to create the current Ilam province. Although established less than 50 years ago, Ilam province's history goes back to millennia ago. This region of Iran was part of the civilization of Elam from 2700 to 539 BC. The modern name of the province comes from the same origin.
  For around a thousand years, Ilam was controlled by Kurds and Lurs: From 961 to 1140 CE, Kurds such as Hasanwayhid and Annazids dynasties ruled; From 1184 to 1597, it was controlled by Little Lor dynasty; and, from 1597 to 1928 by Vali, another Lor dynasty.
