Passage: On 12 April 1204, the weather conditions finally favoured the crusaders. A strong northern wind aided the Venetian ships in coming close to the walls, and after a short battle approximately seventy crusaders managed to enter the city. Some were able to knock holes in the walls, large enough for only a few knights at a time to crawl through; the Venetians were also successful at scaling the walls from the sea, though there was fighting with the Varangians. The Anglo-Saxon "axe bearers" had been amongst the most effective of the city's defenders, but they now attempted to negotiate higher wages from their Byzantine employers, before dispersing or surrendering. The crusaders captured the Blachernae section of the city in the northwest and used it as a base to attack the rest of the city. While attempting to defend themselves with a wall of fire, however, they burned even more of the city. This second fire left 15,000 people homeless. The crusaders completely took the city on 13 April. The crusaders sacked Constantinople for three days, during which many ancient Greco-Roman and medieval Byzantine works of art were stolen or ruined. Many of the civilian population of the city were killed and their property looted. Despite the threat of excommunication, the crusaders destroyed, defiled and looted the city's churches and monasteries. It was said that the total amount looted from Constantinople was about 900,000 silver marks. The Venetians received 150,000 silver marks that was their due, while the crusaders received 50,000 silver marks. A further 100,000 silver marks were divided evenly up between the crusaders and Venetians. The remaining 500,000 silver marks were secretly kept back by many crusader knights. Speros Vryonis in Byzantium and Europe gives a vivid account of the sack:

Passage: The government of Portuguese India started in 1505, six years after the discovery of the sea route to India by Vasco da Gama, with the nomination of the first Viceroy Francisco de Almeida, then settled at Kochi. Until 1752, the name "India" included all Portuguese possessions in the Indian Ocean, from southern Africa to Southeast Asia, governed - either by a Viceroy or Governor - from its headquarters, established in Goa since 1510. In 1752 Portuguese Mozambique got its own government and in 1844 the Portuguese Government of India stopped administering the territory of Portuguese Macau, Solor and Portuguese Timor, seeing itself thus confined to a reduced territorial entity in Malabar: Goa, Daman, Diu, Dadra and Nagar Haveli. Portuguese control ceased in the last two enclaves in 1954, and finally ceased in the remaining three pockets in 1961, when they were occupied by the Republic of India . This ended four and a half centuries of Portuguese rule in partsthought tinyof India. It may be noted that during the term of the monarchy, the title of the head of the Portuguese government in India ranged from "Governor" to "Viceroy". The title of viceroy would only be assigned to members of the nobility; It was formally terminated in 1774, although it has later been given sporadically to be decisively ended after 1835), as shown below.
