The Grand Duchy of Moscow (Russian: Великое Княжество Московское, Velikoye Knyazhestvo Moskovskoye) or Grand Principality of Moscow (also known in English simply as Muscovy) is a medieval state of the Rus' and Far-Eastern Europe. Known for it's revolution against the Polish Lithuanian Union shortly after the beginning of the 15th century. With support from the Teutonic Order (Now Prussia) and a large portion of the Holy Roman Empire, it has annexed half of East Slavic Lithuania, and has a created a vassal previously known as Ukraine. By the year 1405, the Grand Duchy of Moscow has doubled it's territory, but at the price of it's vassals of the Principality of Ustyug which was acquired by the 1420s and the Republic of Pskov. Although, previously being a backwater state within Eastern Europe and home to the Metropolitan and the Curia of the Eastern Orthodox Church, it has prevailed through tough wars and exponentially reunited with their East Slavic and Orthodox brethren in the Rus' by the end of the beginning of the 15th century.



Following the Mongol Invasion of the Rus' in the late 13th century, the nation of the Kiev Rus' was unprepared, ripped apart by the hordes of soldiers that pillaged the region. When the century old Mongol Empire has collapsed due to the death of Toghan Temür Khan, the empire split, into five partitions. Due to this large shattering of an empire, many conquered states declared independence, leaving many cultures disunited, ravaged by the prime successors of the Mongol Empire. Paying tribute, weak, and feeble, Moscow was at first a small trading outpost for the Duchy of Vladimir-Suzdal, hidden in the woods, with access to the Baltic and the Black Sea through various rivers that cut through the region. As trade grew more common in the central region of Moscow, the city state began to grow, acquiring prime influence and power in the Rus'. Although still paying tribute and being pillaged by the Golden Horde, Moscow has prevailed and survived the harsh treatments of it's nearby neighbors. Eventually, it has absorbed its neighboring states, including Vladimir Suzdal, the first signs of the nation erecting as a dominant power in the far-east.



The Grand Duchy of Moscow is considered an absolute monarchy and a tsarists autocracy, due to the authority of the Grand Duke over the controlled region of the Rus'. Although living in a strict totalitarian state where crime is deemed as unholy by most, it is hardened together through national and religious unity for the defense of the nation's sovereignty and people. Since the principal foundings of the Grand Duchy of Moscow, the House of Rurik is the current royal family, who lives in a palace deep inside the walls of the Moscow Kremlin in luxury.

Foreign Relations

At first hated by most of central and eastern Europe, Muscovy has reset relations with many states across the continent after the destruction and separation of the large Polish-Lithuanian Union. This has resulted in the improvement of relations among many states, including the Archduchy of Austria, the Novgorod Republic, the Kingdom of Bohemia, and the Teutonic order that was soon renamed as the Kingdom of Prussia shortly after the war with Poland. With relations anew, trade agreements, alliances, and other pieces of diplomacy were extended. Directly after the Muscovite Crusade which many like to name it as, Muscovy has remained allied with the Novgorod Republic, the Kingdom of Prussia, the Romanian states, and the Pskov Republic. Traders from across the European continent, travel across the nation despite the harsh terrain and weather for rare goods exclusive to the far-east. Nations such as the Crown of Castille, the Kingdom of France, and the Republic of Venice have endorsed trade in the region in order to profit.
