The era when the Silver Kingdoms existed is called the Silver Kingdom Epoch, or the Heraldic Epochs. There were ten kingdoms, each of which had a perfectly palindromic name - a reflection of the holiness of symmetry that can be found in Vorinism. However, it's more than likely that those names predate the rise of Vorin religion.
Each country had its own purpose within the war against the Voidbringers, likely preordained by the Heralds - for example, Alethela was the "protector state", set up to preserve the arts of war and train people in case of a Desolation. All ten states had their own Oathgates within their capital cities, connecting them to the Knight Radiant tower city of Urithiru. Within Urithiru, each of the states is said to have had a throne set up for its ruler.
In the modern era, most of the Silver Kingdoms have splintered, evolved into successor states that lack continuity of government with their ancient antecedents, or ceased to exist entirely, with Shin Kak Nish (now called Shinovar) and perhaps Aimia being the only known exceptions (although the Scouring of Aimia makes its current status unclear). Most, like Makabakam, have splintered into a number of smaller states, while Natanatan has fallen completely, having been reduced to a small number of stateless settlements and a lone city-state of New Natanan. However, the modern cultural, ethnic and linguistic make-up of Roshar still reflects that of those ancient kingdoms, and many current borders lie along similar lines to those of old. Many (though not all) of the splinter states that were once Makabakam give nominal fealty to the ruler of Azir, but these states are not truly united in a political sense. Alethela splintered at some time in the past before eventually being reunited into Alethkar under the Sunmaker. Valhav appears to have undergone a similar process, ultimately succeeded in modern times by Jah Keved. The Silver Kingdom of Iri has been divided into two nations, modern Iri and Rira; it is unknown whether one or both of these states is continuous with the ancient kingdom. Rishir appears to have disappeared entirely, replaced by Herdaz, although it is likely related to the people of the Reshi Isles, which were part of its territory and which contain its Oathgate. Thalath's continental territory is largely ungoverned in the modern age, though it does contain the city state of Kharbranth, but the island nation of Thaylenah appears to be a successor state of some sort. Like Makabakam, the ancient kingdom of Sela Tales is divided in modern times into several nations; little is known about their relationships to each other or to the old kingdom.
