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?
Romance languages

The term "Late Middle Ages" refers to one of the three periods of the Middle Ages, along with the Early Middle Ages and the High Middle Ages. Leonardo Bruni was the first historian to use tripartite periodization in his History of the Florentine People (1442). Flavio Biondo used a similar framework in Decades of History from the Deterioration of the Roman Empire (1439–1453). Tripartite periodization became standard after the German historian Christoph Cellarius published Universal History Divided into an Ancient, Medieval, and New Period (1683).
Along with the Late Middle Ages, what are the other two period of the Middle Ages?
Early Middle Ages and the High Middle Ages

The documentation regarding Raciborz and Albert's tenure is the earliest surviving of the use of the clan name and cry defining the honorable status of Polish knights. The names of knightly genealogiae only came to be associated with heraldic devices later in the Middle Ages and in the early modern period.

The polish anem and cry ritualized what?
the ius militare,
