Westernization of legal institutions and expansion of state control in all areas of law, which began during the colonial era, continued in nation-states of the Muslim world. Sharia courts at first continued to exist alongside state courts as in earlier times, but the doctrine that sultanic courts should implement the ideals of Sharia was gradually replaced by legal norms imported from Europe. Court procedures were also brought in line with European practice. Though the Islamic terms "qadi" and "mahkama" (qadi's/Sharia court) were preserved, they generally came to mean judge and court in the Western sense. While in the traditional Sharia court all parties represented themselves, in modern courts they are represented by professional lawyers educated in Western-style law schools, and the verdicts are subject to review in an appeals court. In the 20th century, most countries abolished a parallel system of Sharia courts and brought all cases under a national civil court system.
