Several of you were curious for a "refresher / update" on what's going on in the world... So I'll gladly oblige!
Europe
Where most of the action has happened, so you're all largely familiar with the current goings-on. Central-western Europe is the seat of most of the world's major powers, with France and Italy as the two most powerful nations in the region, and allied with one another. France in particular boasts the largest standing army in the world. Bavaria is still a subordinate of Italy -- as a refresher to those who may not have followed the CKII portion, the Italian Empire's capitol is in Verona, the long-time home of the Bavarae family's power base. Beneath the Emperor are four subdivisions, each ruled by a Viceroy-King: Bavaria, Pannonia, Sicily, and Tunisia.
Great Britain, Germany, and the Wendish Empire occupy what you might call "middle power" status; they are influential, with the British owning many overseas colonies, and the Germans being a resilient military contender. Frequently cooperating with France and Italy, they get a big piece of the action in Europe. The Wendish Empire is still formidable, but not as tough as it once was. The Wends have maintained a lasting alliance with Russia, and the two combined are a nasty force. Russia has also enjoyed a long alliance with the Byzantine Empire, so those three together comprise a sort of "Eastern equivalent" to the western Grand Alliance. Spain holds many overseas colonies, but is losing power in the mainland as of the last update. Scandinavia and Ruthenia round out the "lesser powers," being allied to one another but both still being relatively militarily incompetent. Ruthenia is also currently allied with France. The Byzantine Empire, of course, is massive, wealthy, and powerful -- however, according to the ledger information, its force limit is slightly lower than both France and Italy. This is offset by the Empire's extreme wealth, such that its army is often substantially over force limit, making it roughly the world's third-largest army, exceeding Italy's substantially.
In terms of religion, Russia and Byzantium are Orthodox, and most of the rest of Europe is all Catholic. Germany is the only Reformed Christian state in the entire world, and Great Britain is the only Protestant country in Europe; Protestant Christianity is much more common in the Americas.
Africa and the Middle East
Africa's northern coast is dominated by the European powers. Spain controls most of northwestern Africa, while Tunisia remains under the control of Italy. Most of the northeastern portion of the continent is under Byzantine occupation, though the trade port in Alexandria belongs to Spain, thanks to their military victories. That little slice of green are the Zeydids, a tiny, two-province country made up of Al Gharbia and Damietta. They represent one of the the last Muslim countries on the planet; the entire Middle East is Christian, and the only other Muslim states are a few small countries in Asia.
Central Africa is largely split between two major African kingdoms -- in the west is Mali, whose ruler is a Bavarae (I'm not really sure I remember when/how that happened, but it did) of a distance branch. In the east is Abyssinia, a large Monophysite Christian kingdom controlling the Horn of Africa. Both kingdoms have separate alliances with the Teutonic Order; Mali is also allied with France. Inside of Mali, landlocked on all sides, is Dagbon, a small westernized African Despotic Monarchy, which has held to ancient Animist religious practices.
In the southern portion of the continent, the tiny kingdom of Kaffa (the little red spot) is home to a very small Coptic Christian minority. France and Spain hold several small colonies that served as their launching pads for sailing further east, and Mali has colonized the island of Madagascar. Of particular interest is Kongo, which is a French protectorate still in the primitive Sub-Saharan technological group. Kongo is Shamanist, a rare thing after most of Africa was Christianized.
The Kingdom of Jerusalem still exists as a sovereign state, and was for centuries a vassal state of the French Empire, who guaranteed its protection from Muslim and Orthodox incursions. However, Jerusalem is currently no longer under French dominion (it looks like the release of Jerusalem was demanded at some point that I missed, as a peace condition by some AI nation). The Teutonic Order has, over the past several centuries, eradicated every remaining Muslim state in the Arabian Peninsula, and has established a lasting Catholic nation-state in the region. It is still ruled by a Grandmaster, making it the only Catholic Knightly Holy Order still active in the world -- its only close counterpart being the Orthodox Brotherhood of the Holy Sepulchre, which still operates from its fortress on Cyprus. The Teutonic lands are organized into smaller governing regions, with the office of Landmeister having become something more akin to the Byzantine office of Strategos; a combination of local governor and military commander. In the past, uprisings of the Muslim population against their Christian overlords were common -- however, after centuries of repression and the censorship of the Quran, this is no longer the case. Much of the native Arabian population is only culturally Catholic; despite the heavy-handed rule of the Teutons, the Arabian region remains one of the most religiously indifferent regions of the world.
Asia
Asia is dominated by two major superpowers -- most of India and the surrounding region is controlled by Hindustan, comprised of a mix of Jain, Hindu, and Buddhist populations. In terms of population and manpower, Hindustan is almost unmatched -- its army size is on par with France's, being the second-largest army in the world as of this moment. Despite its incredible power, Hindustan has rarely shown interest in territorial expansion. The southern tip of India is controlled by a few smaller Indian nations and several European colonizers, and minimal conquest has taken place for several centuries.
In contrast, Ming China -- now a Feudal Monarchy ruled by the Zhu dynasty -- has rapidly become one of the leading aggressive conquerors in the world. Ming has gradually swallowed up its Asian competitors, and devoured large portions of land previously held by the Timurids and other Steppe peoples.
Indochina is split between Lan Na, Lan Xing, Khmer, and Malacca -- Malacca being the largest Sunni Islamic state in the world. Australia has been colonized by Byzantium, Brittany, and Mali who, together with France, are the major players in colonizing the nearby islands.
South America
South America is perhaps the most stable region in the world. While a small number of tiny native regions remain independent, the continent is almost entirely divided in three -- Italian Brazil in the east, Spanish Peru and La Plata in the south, and British Peru and Colombia in the north. The local colonial troops have, at times, skirmished with each other when their European parent nations were at war, but very little has changed in South America for some time. However, the South American colonies are among the most independent, and the Spanish and Italian colonies in particular have been home to growing independence movements.
North America
While South America has remained stable and tranquil, North America has seen quite a bit more conflict. Brittany was at one time considered the strongest state in North America, but the Bretons have fallen on hard times after European powers have declared a string of wars against them. Several Native American tribes have risen up and claimed their independence, and Mali has claimed a portion of the region as the spoils of war, as well.
Along the eastern coast, New Italy has remained a stable colony for many years and, unlike Brazil, has proven very loyal and friendly toward the Lombards at home. In the mid 18th century, the Republic of Powhatan, -- a vassal of Italy in which the settlement of colonists has been forbidden -- underwent a political revolution and became the Duchy of Powhatan, organized as an Absolute Monarchy under a single tribal leader. Newfoundland and the Thirteen Colonies, both under British control, occupy much of the northeastern region, and Nova Scotia, a small state built by Catholic refugees from Scotland, holds on to small areas of land as well.
While several small Native American tribes remain, none have been as successful or resilient as the Sioux. The Sioux enjoyed an extended prosperous relationship with Great Britain in particular, but other regional powers as well. The Sioux people converted to Protestantism in imitation of their British friends and, after westernizing, have maintained a stable Administrative Monarchy in the Great Lakes region. They are the most technologically advanced of all the Native Americans, and have greatly integrated western customs into their society.
On the west coast, the Spanish colonies of Pacifico Norte and Oregon border the Byzantine colony of California, and the two have often come to blows during wars in mainland Europe. These struggles have tended to favor the Spanish, who have on several occasions occupied California in extended campaigns.
To the south, Mexico -- which was founded by Scottish Protestants who fled in the wake of England's conquest of their homeland -- has come out on the winning end of military clashes with Spanish colonies in the region, and has taken land from nearby Native groups to become the largest power in the southern regions of America. New Spain is bisected by Mexico, and colonies to the south ruled by France and Nova Scotia have lacked comparable military strength. The strongest true colony in the region is, surprisingly, the French Antilles, which have contributed naval and land forces to several French wars in the region, notably during the most recent war of the Grand Alliance against Spain.
