Marches in the context of "Duchy of Tridentum"

The Danes were a North Germanic tribe inhabiting southern Scandinavia, including the area now comprising Denmark proper, northern and eastern England, and the Scanian provinces of modern-day southern Sweden, during the Nordic Iron Age and the Viking Age. They founded what became the Kingdom of Denmark. The name of their realm is believed to mean "Danish March", viz. "the march of the Danes", in Old Norse, referring to their southern border zone between the Eider and Schlei rivers, known as the Danevirke.

The Battle of Vouillé (from Latin Campus Vogladensis) was fought in the northern marches of Visigothic territory, at Vouillé, near Poitiers (Gaul), around Spring 507 between the Franks, commanded by Clovis, and the Visigoths, commanded by Alaric II. The Franks' victory resulted in their conquest of Gallia Aquitania and the death of Alaric II.

The Sorbian March (Latin: limes Sorabicus, German: Sorbenmark, Upper Sorbian: Serbska marka, Lower Sorbian: Serbska marka) was a frontier district on the eastern border of East Francia in the 9th through 11th centuries. It was composed of several counties bordering the Sorbs. The Sorbian March seems to have comprised the eastern part of Thuringia.

The Sorbian March was sometimes referred to as the Thuringian March. The term "Sorbian March" appears only four times in the Annales Fuldenses.

The etymology of the name Denmark (Danish: Danmark), especially the relationship between Danes and Denmark and the unification of Denmark as a single kingdom, is the cause of some debate. In Old Norse, the country was called Danmǫrk, referring to the Danish March, viz. the marches of the Danes.

According to medieval origin legend, the name Denmark refers to the mythological King Dan. There are also a number of references to various Dani people in Scandinavia or other places in Europe in Greek and Roman accounts (like Ptolemy, Jordanes, and Gregory of Tours), as well as some medieval literature (like Adam of Bremen, Beowulf, Widsith and Poetic Edda).

The terms Danish March and March of Schleswig (German: Dänische Mark or Mark Schleswig) are used to refer to a territory in modern-day Schleswig-Holstein north of the Eider and south of the Danevirke. It was established in the Early Middle Ages as a March of the Frankish Empire to defend against the Danes. The term "Danish March" is a modern designation not found in mediaeval sources. According to the Royal Frankish Annals, the Danish King led his troops "into the March" in 828 (ad marcam). In the 852 Yearbook of Fulda, there is mention of a "Guardian of the Danish Border" (custodes Danici limitis).

In Old Norse, Denmark was called Danmǫrk, viz. the marches of the Danes. The Latin name is Dania.

Alfonso IV (c. 890s – 933), called the Monk (Spanish: el Monje), was King of León from 925 (or 926) and King of Galicia from 929, until he abdicated in 931.

When Ordoño II died in 924 it was not one of his sons who ascended to the throne of León but rather his brother Fruela II of Asturias. The exact circumstances of the succession upon Fruela's death one year later are unclear, but the son of Fruela, Alfonso Fróilaz, became king in at least part of the kingdom when his father died. Sancho Ordóñez, Alfonso, and Ramiro, the sons of Ordoño II, claimed to be the rightful heirs and rebelled against their cousin. With the support of king Jimeno Garcés of Pamplona, they drove Alfonso Fróilaz to the eastern marches of Asturias, and divided the kingdom among themselves with Alfonso Ordóñez receiving the crown of León and his elder brother Sancho being acclaimed king in Galicia.

The Matsumae clan (松前氏, Matsumae-shi) was a Japanese aristocratic family who were daimyo of Matsumae Domain, in present-day Matsumae, Hokkaidō, from the Azuchi–Momoyama period until the Meiji Restoration. They were given the domain as a march fief in 1590 by Toyotomi Hideyoshi, and charged with defending it, and by extension the whole of Japan, from the Ainu "barbarians" of the north. They were the first Japanese to negotiate with Russia in any way. Following the Meiji Restoration, the family was bestowed the title of Viscount.

The March of Verona and Aquileia was a vast march (frontier district) of the Holy Roman Empire in the northeastern Italian region during the Middle Ages, centered on the cities of Verona and Aquileia. Seized by King Otto I of Germany in 952, it was held by the Dukes of Bavaria; from 976 in personal union with the Duchy of Carinthia. The margravial regime ended with the advent of the Lombard League in 1167.

The Marca Geronis or March of Gero was a vast super-march in the middle of the tenth century. It was probably created for Thietmar in the 920s and passed consecutively to his two sons, Siegfried and Gero. On Gero's death in 965 it was divided into five different marches: the Nordmark, Ostmark, Meissen, Zeitz, and Merseburg.

Because Siegfried's and Gero's comital seat was Merseburg, it has sometimes been called the March of Merseburg. However, there is also a Merseburger march which grew out of it after 965. Because the central diocese in his march was Magdeburg, it is sometimes called the March of Magdeburg. Other historians prefer to call it the Saxon Eastern March or Ostmark, but these terms are also applied to another march which grew out of it in 965. Because the Marca Geronis was created simultaneously with the March of Billung to the north, it is sometimes said to be the southern half of the Ostmark. Some historians even call it the "March of Meissen." Within the span of one page, James Westfall Thompson refers to it as both the "Sorben Mark" and the "Thuringian March".

The Military Frontier was a borderland of the Habsburg monarchy and later the Austrian and Austro-Hungarian Empire. It acted as the cordon sanitaire against incursions from the Ottoman Empire.

The establishment of the new defense system in Hungary and Croatia took place in the 16th century, following the election of Ferdinand I as king. Six districts under special military administration were established in Hungary and Croatia. The Croatian Military Frontier and the Slavonian Military Frontier came under the jurisdiction of the Croatian Sabor and ban. In 1627, they were placed under the direct control of the Habsburg military. For more than two centuries, they would retain complete civilian and military authority over the area, up to the abolition of the Military Frontier in 1881.

The County of Aragon (Aragonese: Condato d'Aragón) or County of Jaca (Aragonese: Condato de Chaca) was a small Frankish marcher county in the central Pyrenean valley of the Aragon river, comprising Ansó, Echo, and Canfranc and centered on the small town of Jaca (Iacca in Latin and Chaca in Aragonese), an area now part of Spain. It was created by the Carolingians late in the 8th or early in the 9th century, but soon fell into the orbit of the Kingdom of Navarre, into which it was absorbed in 922. It would later form the core of the 11th century Kingdom of Aragon.

The Principality or Margraviate of (Brandenburg) Ansbach (German: Fürstentum Ansbach or Markgrafschaft Brandenburg-Ansbach) was a free imperial principality in the Holy Roman Empire centered on the Franconian city of Ansbach. The ruling Hohenzollern princes of the land were known as margraves, as their ancestors were margraves (so the principality was a margraviate but not a march).
