Final answer:
Belarus is the country also known as White Russia, which is a direct translation of its name from Slavic languages.
Step-by-step explanation:
The country commonly referred to as White Russia is Belarus. This alternative name is directly translated from its name in various Slavic languages, including Russian, where it is called Беларусь (Belarus'). Historically, the term may have been used to distinguish the region from 'Black Russia' and 'Red Russia,' whose historical territories are in parts of modern-day Belarus, Ukraine, and Russia.
While not much information is available in the sources provided regarding the specific term 'White Russia,' this nomenclature is often understood in a historical context where names and boundaries of countries have frequently changed. Today, Belarus is an independent country, having declared its independence from the Soviet Union in 1991. Its history, like that of many other countries in the region, is a tapestry of various cultural and political influences ranging from its medieval origins to the modern era.
