Education in Madagascar has a long and distinguished history. Formal schooling began with medieval Arab seafarers, who established a handful of Islamic primary schools (kuttabs) and developed a transcription of the Malagasy language using Arabic script, known as sorabe. These schools were short-lived, and formal education was only to return under the 19th-century Kingdom of Madagascar when the support of successive kings and queens produced the most developed public school system in precolonial Sub-Saharan Africa. However, formal schools were largely limited to the central highlands around the capital of Antananarivo and were frequented by children of the noble class andriana. Among other segments of the island's population, traditional education predominated through the early 20th century
