Ertugrul, the father of Osman I (founder of the Ottoman Empire), arrived in Anatolia from Merv (Turkmenistan) with 400 horsemen to aid the Seljuks of Rum against the Byzantines. After the demise of the Turkish Seljuk Sultanate of Rum in the 14th century, Anatolia was divided into a patchwork of independent, mostly Turkish states, the so-called Ghazi emirates. One of the emirates was led by Osman I (12581326), from whom the name Ottoman is derived. Osman I extended the frontiers of Turkish settlement toward the edge of the Byzantine Empire. It is not well understood how the early Ottomans came to dominate their neighbours, as the history of medieval Anatolia is still little known.

How many horsemen did Osman I's father bring to aid the Seljuks of Rum?
Answer: 400 horsemen

The invasions brought new ethnic groups to Europe, although some regions received a larger influx of new peoples than others. In Gaul for instance, the invaders settled much more extensively in the north-east than in the south-west. Slavic peoples settled in Central and Eastern Europe and the Balkan Peninsula. The settlement of peoples was accompanied by changes in languages. The Latin of the Western Roman Empire was gradually replaced by languages based on, but distinct from, Latin, collectively known as Romance languages. These changes from Latin to the new languages took many centuries. Greek remained the language of the Byzantine Empire, but the migrations of the Slavs added Slavonic languages to Eastern Europe.

What is the collective name for languages derived from Latin?
Answer:
Romance languages
