History of Germany between 844 AD - 918 AD
In medieval historiography, East Francia or the Kingdom of the East Franks forms the earliest stage of the Kingdom of Germany, lasting from about 840 until about 962. East Francia was formed out of the division of the Carolingian Empire after the death of Emperor Louis the Pious.
In August 843, after three years of civil war following the death of Louis the Pious, the Treaty of Verdun was signed by his three sons and heirs. His namesake, Louis the German, received the eastern portion of mostly Germanic-speaking lands. The kingdom of West Francia went to Louis's younger half-brother Charles the Bald and between their realms a kingdom of Middle Francia, incorporating Italy, was given to their elder brother, the Emperor Lothair I. While West and Middle Francia contained the traditional Frankish 'heartlands', the East consisted mostly of lands only annexed to the Frankish empire in the eighth century. These included the duchies of Alemannia, Bavaria, Saxony and Thuringia, as well as the northern and eastern marches with the Danes and Slavs.
The external threat from marauding Vikings in the west and from Magyars in the east aggravates an already grave internal problem for the feudal dynasties of Charlemagne's descendants. Feudalism, with its decentralization of military and territorial power, has at the best of times a tendency to foster regional independence. In periods of crisis, when the regions need to be well armed if they are to repel invaders, it is almost inevitable that the feudal holders of large tracts of frontier territory grow in strength until they are capable of challenging their own king. Baronial contenders upset the succession to the throne in the west Frankish kingdom from the late 9th century and in the eastern kingdom a few years later.
In 911 the east Frankish king Louis the Child died without a male heir. The only legitimate claimant within the Carolingian dynasty is Charles III, ruler of the west Frankish kingdom. Rather than do homage to him, and reunite the empire of Charlemagne, the eastern Franks and the Saxons elected one of their own number to the vacant throne. Conrad, the duke of Franconia, became the German king. Although not of the Carolingian line, Conrad is nevertheless a Frank. But on his death the Franks and the Saxons together elect a Saxon king. In 919 Henry I becomes the founder of the Saxon, or Ottonian, dynasty.
The Palazzo Colonna is a palatial block of buildings built in part over ruins of an old Roman Serapeum, and has belonged to the prestigious Colonna family for over twenty generations.
The first part of the palace dates from the 13th century, and tradition holds that the building hosted Dante in his visit to Rome. The first documentary mention notes that the property hosted Cardinal Giovanni and Giacomo Colonna in the 13th century. It was also home to Cardinal Oddone Colonna before he ascended to the papacy as Martin V (1417–1431).
With his passing, the palace was sacked during feuds, and the main property passed into the hands of the Della Rovere family. It returned to the Colonna family when Marcantonio I Colonna married Lucrezia Gara Franciotti Della Rovere, the niece of pope Julius II. The Colonna"s alliance to the Habsburg power, likely protected the palace from looting during the Sack of Rome (1527).
Starting with Filippo Colonna (1578–1639) many changes have refurbished and create a unitary complex around a central garden. Architects including Girolamo Rainaldi and Paolo Marucelli labored on specific projects. Only in the 17th and 18th centuries were the main facades completed. Much of this design was completed by Antonio del Grande (including the grand gallery), and Girolamo Fontana (decoration of gallery). In the 18th century, the long low facade designed by Nicola Michetti with later additions by Paolo Posi with taller corner blocks (facing Piazza Apostoli) was constructed recalls earlier structures resembling a fortification.
The main gallery (completed 1703) and the masterful Colonna art collection was acquired after 1650 by both the cardinal Girolamo I Colonna and his nephew the Connestabile Lorenzo Onofrio Colonna and includes works by Lorenzo Monaco, Domenico Ghirlandaio, Palma the Elder, Salviati, Bronzino, Tintoretto, Pietro da Cortona, Annibale Carracci (painting of The Beaneater), Guercino, Francesco Albani, Muziano and Guido Reni. Ceiling frescoes by Filippo Gherardi, Giovanni Coli, Sebastiano Ricci, and Giuseppe Bartolomeo Chiari celebrate the role of Marcantonio II Colonna in the battle of Lepanto (1571). The gallery is open to the public on Saturday mornings.
The older wing of the complex known as the Princess Isabelle"s apartments, but once housing Martin V"s library and palace, contains frescoes by Pinturicchio, Antonio Tempesta, Crescenzio Onofri, Giacinto Gimignani, and Carlo Cesi. It contains a collection of landscapes and genre scenes by painters like Gaspard Dughet, Caspar Van Wittel (Vanvitelli), and Jan Brueghel the Elder.
Along with the possessions of the Doria-Pamphilij and Pallavacini-Rospigliosi families, this is one of the largest private art collections in Rome.
