Der Begriff Mohr ist eine seit dem Mittelalter verwendete Bezeichnung für Menschen mit dunkler Hautfarbe, zum Beispiel historisch in Bezug auf Kuschiter und Mauren oder später allgemeiner für Schwarzafrikaner. Sie wird heute aufgrund ihrer negativen Konnotation nur noch selten gebraucht.
Translation:
The term Moor is used since the Middle Ages term for people with dark skin color, such as historical for the Ethiopians and Moors or later generalized for black Africans. It is now rarely used because of its negative connotation.
Ursprünglich bezeichnete das mittelhochdeutsche Wort mōr[1] einen Mauren. Der Begriff Maure stammt allerdings vom Griechischen μαῦρος, was soviel wie „schwarz, dunkel, dunkelhäutig, dunkelhaarig“ bedeutet. Mauretanien bedeutet daher zunächst das Land der Dunkelhäutigen. Das lateinische maurus kennzeichnet in aller Regel bereits den Mauren als Herkunftsbezeichnung (aus der Provinz Mauretania bzw. dem Königreich Mauretanien).
Im Mittelhochdeutschen wurde dann nicht selten zwischen swarzer mōr („Maure mit dunkler Hautfarbe“) und mōr („Maure“) differenziert. Sogar heute noch findet sich im Deutschen die Bezeichnung schwarzer Mohr, was man aber eher als unnötige Doppelung (Tautologie) oder als literarische Betonung empfindet. Sehr früh belegt ist auch die Verbindung von mōr und Ethiops.
Translation:
Originally designated the Middle High German word MOR [1 ] a Moor . However, the term Moor comes from the Greek μαῦρος , which means " black, dark , dark-skinned, dark-haired 'means . Mauritania therefore initially means the land of dark-skinned people . The Latin maurus features usually already the Moors as a designation of origin ( from the province of Mauretania and the Kingdom of Mauritania) .
In Middle High German then often between swarzer Mor ( " Moor with dark skin " ) and MOR ( " Moor ") was differentiated. Even today, can be found in German the term black Mohr, but you'd rather be an unnecessary duplication ( tautology ), or feels as literary emphasis. Occupied very early is the combination of MOR and Ethiops .
As in the 18th Century was the term " Moor " then increasingly by the term " ****** " replaced , there was the possibility for comparison of noble Mohr ( pre-colonial idea ) and primitive Negro ( colonial idea ) . Even the attempt to distinguish between black African " Negroes " and white African differentiate " Moors " in the wake of racial theories , is now obsolete.The term Mohr for a dark-skinned person is now used only in historical contexts. Like the term " negro " can be understood as a racially discriminatory term " Moor " .
They're saying in the 18th century they stopped using Moor and started using ******, Moor being the pre colonial idea of blacks and ****** being the primitive negro (the new colonial idea. That makes sense because if you look up "black" in old dictionarys you will see Moor their as well. This dude made a video about that:
The truth
Props on that video breh.
Its also interesting that Portugal was the first to start poaching African slaves. The same region the Moors controlled 100 years earlier
