Casablanca (Spanish for white (blanca) house (casa) ; Amazigh: Anfa; Standard Arabic: الدار البيضاء; Moroccan Arabic: dar beïda الدار البيضا ) is a city in western Morocco, located on the Atlantic Ocean. It is the capital of the Greater Casablanca region.

With a population of 3.1 million (3.85 million in the "greater Casablanca" (September 2005 census), Casablanca is Morocco's largest city as well as its chief port. It's also the biggest city in the Maghreb and the sixth biggest city in the entire continent of Africa. Casablanca is considered the economic capital of Morocco because it is the heart of Moroccan business; the political capital is Rabat. It is also the primary naval base for the Royal Moroccan Navy.

Casablanca is the leading city hosting headquarters and main industrial facilities for the leading Moroccan and international companies based in Morocco. Industrial statistics show Casablanca retains its historic position as the main industrial zone of the country. The Port of Casablanca is considered as Morocco's chief port and as one of the largest artificial ports in the world. It is also the largest port of the Maghreb and North Africa.

The area which is today Casablanca was settled by Berbers by at least the 7th century. A small independent kingdom, in the area then named Anfa, arose in the area around that time in response to Arab Muslim rule, and continued until it was conquered by the Almoravids in 1068.

During 14th century, under the Merinids, Anfa rose in importance as a port. In the early 15th century, the town became an independent state once again, and emerged as a safe harbour for pirates and privateers, leading to it being targeted by the Portuguese, who destroyed the town in 1468.

The Portuguese used the ruins of Anfa to build a military fortress in 1515. The town that grew up around it was called "Casabranca", meaning "White House" in Portuguese.

Between 1580-1640 was part of Spain, and later part of Portugal again. They eventually abandoned the area completely in 1755 following an earthquake which destroyed most of the town.

The town was finally reconstructed by sultan Mohammed ben Abdallah (1756-1790), the grandson of Moulay Ismail and ally of George Washington. The town was called Dar el Beida (white house) in Arabic and Casa Blanca in Spanish.

In the 19th century, the area's population began to grow as Casablanca became a major supplier of wool to the booming textile industry in Britain and shipping traffic increased (the British, in return, began importing Morocco's now famous national drink, gunpowder tea). By the 1860s, there were around 5,000 residents, and the population grew to around 10,000 by the late 1880s. Casablanca remained a modestly-sized port, with a population reaching around 12,000 within a few years of the French conquest and arrival of French colonialists in the town, at first administrators within a sovereign sultanate, in 1906. By 1921, this was to rise to 110,000 largely through the development of bidonvilles.
