Suryavarman dispatches his greatest general, Senapati Sankara, at the head of a combined Khmer-Vijayan force to attack the relocated Cham capital in 1147.

Jaya Harivarman meets Sankara’s army at Chaklyang in the Phanrang valley and annihilates it.

The Chams, following the Khmer invasion and conquest of the Cham capital of Vijaya, install Rudravarman as ruler in Panduranga, which becomes the provisional capital of Champa.

Following King Rudravarman’s death in 1147, his son succeeds him as Jaya Harivarman I.

Albert the Bear, ruler of the Nordmark and some valuable lands in northern Saxony, had on his mother's death in 1142 succeeded to one-half of the lands of the House of Billung, which had been the primary ruling dynasty in Saxony in the tenth and eleventh centuries, and for which reason Albert has become embroiled in a low-intensity feud with the Welf dukes of Saxony.

Now firmly established in the Nordmark, Albert casts his covetous eye on the lands to the north and east that are thinly populated the Slavic Wends, who as pagans are considered fair game, and whose subjugation to Christianity is the aim of the German "Wendish crusade" of 1147 authorized by the Roman Catholic church and led by Henry the Lion, and in which Albert takes part.

Vienna has become an important center of German civilization in central Europe by the middle of the twelfth century, and the four existing churches, including only one parish church, no longer meet the town's religious needs.

In 1137, Bishop of Passau Reginmar and Margrave Leopold IV had signed the Treaty of Mautern, which referred to Vienna as a civitas for the first time and transferred the St. Peter's Church to the Diocese of Passau.

Under the treaty, Margrave Leopold IV also received from the bishop extended stretches of land beyond the city walls, with the notable exception of the territory allocated for the new parish church, which will eventually become St. Stephen's Cathedral.

Founded in 1137 following the Treaty of Mautern, the partially constructed Romanesque church is solemnly dedicated in 1147 to Saint Stephen in the presence of Conrad III of Germany, Bishop Otto of Freising, and other German nobles who are about to embark on the Second Crusade.

Henry III, a member of the Welf dynasty and Duke of Saxony, is the son of Henry the Proud, Duke of Bavaria and Saxony, who was the son of Duke Henry the Black and an heiress of the Billungs, former dukes of Saxony.

Henry's mother is Gertrud, only daughter of Emperor Lothair III and his wife Richenza of Northeim, heiress of the Saxon territories of Northeim and the properties of the Brunones, counts of Braunschweig.

Henry's father had died in 1139, aged thirty-two, when Henry was still a child.

King Conrad III had dispossessed Henry the Proud, who had been his rival for the German crown in 1138, of his duchies in 1138 and 1139, handing Saxony to Albert the Bear and Bavaria to Leopold of Austria.

Henry, however, had not relinquished his claims to his inheritance, and Conrad had returned Saxony to him in 1142.

Having reached his majority in 1146, Henry in 1147 marries Clementia of Zähringen, thereby gaining her hereditary territories in Swabia.

Upon the refusal of Conrad III to grant his demand of the Duchy of Bavaria, Henry initiates a war with the emperor, who is absent in Palestine with France’s Louis VII.

As Henry the Lion, he is to become one of the most powerful German princes of his time.

Fridianus (Frediano), an Irish bishop of Lucca in the first half of the sixth century, had had a church built in Lucca dedicated to St. Vincent, a martyr from Zaragoza, Spain.

When Fridianus was buried in this church, the church was renamed Ss.

Frediano and Vincenzo.

Soon afterwards, a community of Augustinian canons was growing around this church.

In the Longobard era, the church and the canon house had been enlarged.

In 1104, this order had been recognized by Pope Paschal II.

The prior of St. Frediano was later accorded a rank equal in dignity to that of a bishop.

The Romanesque church, known as the Basilica of San Frediano, acquires its present appearance of a typical Roman basilica during the period 1112-1147.

Al-Mumin’s forces had moved west onto the Atlantic coastal plain after defeating the Almoravids in open battle.

After laying siege to Marrakech, they finally capture it in 1147, killing Ishaq ibn Ali, the last Almoravid ruler in Marrakech, in 1147 and establishing Marrakech as the Almohad capital.

After the capture of Marrakech, Abd al-Mu'min orders the elimination of thirty thousand Almoravids in a purge to quell any open rebellions.

The Almohads offer Christians and Jews the choice of conversion or expulsion.

Many Jews convert but continue to practice Judaism in secret.

Hildegard, after splitting from the monastery at Disibodenberg, founds a new convent at Rupertsberg, near Bingen, in about 1147, by which time she has begun dictating her mystical visions to a monk.

She had acquired the land from Hermann, dean of Mainz, and Count Bernhard of Hildesheim, plus various smaller gifts.

Prince David, prior to his ascension to the Scottish throne, had in 1118 established a foundation of canons regular of the order of St. Augustine at, what is now Jedburgh.

The foundation appeared to have the status of 'priory' in the early years and a man by the name of Daniel was in 1139 described as the Prior of Geddwrda.

The church was later raised to the status of monastery before becoming in the years prior to King David's death in 1153, probably in 1147, a fully fledged abbey and dedicated to the Virgin Mary.

It must be mentioned that over the years, Jedburgh has been described by eighty-three different names or spellings.
