Warum fehlt auf der deutschen Seite die deutsche Form "Laskar"?

A lascar was a sailor or militiaman from the Indian Subcontinent, Southeast Asia, the Arab world, and other territories located to the east of the Cape of Good Hope, who were employed on European ships from the 16th century until the middle of the 20th century.  The Persian word lashkar (army) derives from al-askar, the Arabic word for a guard or soldier. The Portuguese adapted this term to "lascarin", meaning Asian militiamen or seamen, specifically from any area east of the Cape of Good Hope. This means that Indian, Malay, Chinese and Japanese crewmen were covered by the Portuguese definition. The British of the East India Company initially described Indian lascars as 'Black Portuguese' or 'Topazes', but later adopted the Portuguese name, calling them 'lascar'. Lascars served on British ships under "lascar agreements." These agreements allowed shipowners more control than was the case in ordinary articles of agreement. The sailors could be transferred from one ship to another and retained in service for up to three years at one time. The name lascar was also used to refer to Indian servants, typically engaged by British military officers.
