Salian dynasty in the context of "Stem duchy"

Matilda of Tuscany (Italian: Matilde di Toscana; Latin: Matilda or Mathilda; c. 1046 – 24 July 1115), or Matilda of Canossa (Italian: Matilde di Canossa [maˈtilde di kaˈnɔssa]), also referred to as la Gran Contessa ("the Great Countess"), was a member of the House of Canossa (also known as the Attonids) in the second half of the eleventh century. Matilda was one of the most important governing figures of the Italian Middle Ages. She reigned in a time of constant battles, political intrigues, and excommunications by the Church.

She ruled as a feudal margravine and, as a relative of the imperial Salian dynasty, she brokered a settlement in the so-called Investiture Controversy. In this extensive conflict with the emerging reform Papacy over the relationship between spiritual (sacerdotium) and secular (regnum) power, Pope Gregory VII dismissed and excommunicated the Holy Roman Emperor Henry IV (then King of the Romans) in 1076. At the same time, Matilda came into possession of a substantial territory that included present-day Lombardy, Emilia, Romagna, and Tuscany. She made the Canossa Castle, in the Apennines south west of Reggio Emilia, the centre of her domains.

An Imperial Estate (Latin: Status Imperii; German: Reichsstand, plural: Reichsstände) was an entity or an individual of the Holy Roman Empire with representation and the right to vote in the Imperial Diet (Reichstag). Rulers of these Estates were able to exercise significant rights and privileges and were "immediate", meaning the only authority above them was that of the Holy Roman Emperor. They were thus able to rule their territories with a considerable degree of autonomy.

The system of imperial states replaced the more regular division of Germany into stem duchies in the early medieval period. The old Carolingian stem duchies were retained as the major divisions of Germany under the Salian dynasty, but they became increasingly obsolete during the early high medieval period under the Hohenstaufen, and they were finally abolished in 1180 by Frederick Barbarossa in favour of more numerous territorial divisions. From 1489, the Imperial Estates represented in the Diet were divided into three chambers, the college of prince-electors (Kurfürstenkollegium/den Kurfürstenrat), the college of imperial princes (Reichsfürstenrat) and the college of imperial cities. Counts and nobles were not directly represented in the Diet in spite of their immediate status, but were grouped into "benches" (Grafenbänke) with a single vote each.Imperial Knights and imperial villages had immediate status but were not represented in the Diet.

Henry IV (German: Heinrich IV; 11 November 1050 – 7 August 1106) was Holy Roman Emperor from 1084 to 1105, King of Germany from 1054 to 1105, King of Italy and Burgundy from 1056 to 1105, and Duke of Bavaria from 1052 to 1054. He was the son of Henry III, Holy Roman Emperor—the second monarch of the Salian dynasty—and Agnes of Poitou. After his father's death on 5 October 1056, Henry was placed under his mother's guardianship. She made grants to German aristocrats to secure their support. Unlike her late husband, she could not control the election of the popes, thus the idea of the "liberty of the Church" strengthened during her rule. Taking advantage of her weakness, Archbishop Anno II of Cologne kidnapped Henry in April 1062. He administered Germany until Henry came of age in 1065.

Henry endeavoured to recover the royal estates that had been lost during his minority. He employed low-ranking officials to carry out his new policies, causing discontent in Saxony and Thuringia. Henry crushed a riot in Saxony in 1069 and overcame the rebellion of the Saxon aristocrat Otto of Nordheim in 1071. The appointment of commoners to high office offended German aristocrats, and many of them withdrew from Henry's court. He insisted on his royal prerogative to appoint bishops and abbots, although the reformist clerics condemned this practice as simony (a forbidden sale of church offices). Pope Alexander II blamed Henry's advisors for his acts and excommunicated them in early 1073. Henry's conflicts with the Holy See and the German dukes weakened his position and the Saxons rose up in open rebellion in the summer of 1074. Taking advantage of a quarrel between the Saxon aristocrats and peasantry, he forced the rebels into submission in October 1075.

Henry III (German: Heinrich III, 28 October 1016 – 5 October 1056), called the Black (German: Heinrich der Schwarze) or the Pious, was Holy Roman Emperor from 1046 until his death in 1056. A member of the Salian dynasty, he was the eldest son of Conrad II and Gisela of Swabia.

Henry was raised by his father, who made him Duke of Bavaria in 1026, appointed him co-ruler in 1028 and bestowed him with the duchy of Swabia and the Kingdom of Burgundy ten years later in 1038. The emperor's death the following year ended a remarkably smooth and harmonious transition process towards Henry's sovereign rule, that was rather uncharacteristic for the Ottonian and Salian monarchs. Henry succeeded Conrad II as Duke of Carinthia and King of Italy and continued to pursue his father's political course on the basis of virtus et probitas (courage and honesty), which led to an unprecedented sacral exaltation of the kingship. In 1046 Henry ended the papal schism, was crowned Emperor by Pope Clement II, freed the Vatican from dependence on the Roman nobility and laid the foundation for its empire-wide authority. In the duchies, Henry enforced the sovereign royal right of disposition, thereby ensuring tighter control. In Lorraine, this led to years of conflict from which he emerged victorious. Another sphere of defiance formed in southern Germany from 1052 to 1055. Henry III died in 1056, aged only 39. Modern historians identify the final years of his reign as the beginning of a crisis in the Salian monarchy.

Ottonian art is a style in pre-romanesque German art, covering also some works from the Low Countries, northern Italy and eastern France. It was named by the art historian Hubert Janitschek after the Ottonian dynasty which ruled Germany and Northern Italy between 919 and 1024 under the kings Henry I, Otto I, Otto II, Otto III and Henry II. With Ottonian architecture, it is a key component of the Ottonian Renaissance (circa 951–1024). However, the style neither began nor ended to neatly coincide with the rule of the dynasty. It emerged some decades into their rule and persisted past the Ottonian emperors into the reigns of the early Salian dynasty, which lacks an artistic "style label" of its own. In the traditional scheme of art history, Ottonian art follows Carolingian art and precedes Romanesque art, though the transitions at both ends of the period are gradual rather than sudden. Like the former and unlike the latter, it was very largely a style restricted to a few of the small cities of the period, and important monasteries, as well as the court circles of the emperor and his leading vassals.

After the decline of the Carolingian Empire, the Holy Roman Empire was re-established under the Saxon Ottonian dynasty. From this emerged a renewed faith in the idea of Empire and a reformed Church, creating a period of heightened cultural and artistic fervour. It was in this atmosphere that masterpieces were created that fused the traditions from which Ottonian artists derived their inspiration: models of Late Antique, Carolingian, and Byzantine origin. Surviving Ottonian art is very largely religious, in the form of illuminated manuscripts and metalwork, and was produced in a small number of centres for a narrow range of patrons in the circle of the Imperial court, as well as important figures in the church. However much of it was designed for display to a wider public, especially of pilgrims.
