In the northern point of the Adriatic Sea lay the city of Venice, built upon a cluster of little islands. The people had taken refuge there when Italy was overrun by the barbarians. In course of time these Venetians had grown to be a mighty and powerful people, whose merchant ships traded all over the Mediterranean, and whose counsellors were famed for wisdom. They had shaken off the power of the Greek emperor, and were governed by a senate and council, with a chosen nobleman at its head, who was called the Doge, or Duke. Just when the French, Germans, and Italians were setting off on the Fourth Crusade, in the year 1201, meaning to sail in Venetian ships, the young Alexius Angelus, son to the emperor Isaac Angelus, came to beg for help for his poor old father, who had been thrown into prison by his own brother, with his eyes put out. It was quite aside from the main work of the Crusade, but the Venetians had always had a quarrel with the Greek emperors, and they prevailed to turn the army aside to attack Constantinople. With an immense pair of shears they cut in twain the great chains which shut in the harbour of the Golden Horn, and sailed safely in, led by their Doge, Dandolo, who, though eighty years old, and blind, was as keen on the battle as the youngest man there. The French scaled the walls, the usurper fled, and blind old Isaac was led out of his dungeon, and dressed in his robes again; his son was crowned to reign with him, and they did everything to please the Crusaders. Chiefly they made the Patriarch of Constantinople consent to give up all the differences with the Roman Catholic Church, and own the Pope as superior to him. This made the Greeks angry, and they could not bear to see their young emperor so familiar with the French knights, whom they looked on as barbarians. One day he was seen with a Frenchman’s cap on his head, and his own crown lying on the ground at his feet. In great anger the people of Constantinople rose, under a man named Alexius Ducas, called “Black-brows,” murdered the two emperors, and set up this new one; but he did not reign long, for the French and Venetians were close at hand. There was a second siege, and when the city was taken they plundered it throughout, stripped it of all the wealth they could collect, and set up Baldwin, Count of Flanders, to be emperor, with a Latin Patriarch; while the Venetians helped themselves to all the southern part of the empire, namely, the Peloponnesus and the Greek islands; and a French nobleman named Walter de Brienne was created Duke of Athens, under the Flemish emperor.
