Input: At the same time, the Dutch organized incursions against the Portuguese possessions in Africa in order to take control of the slave trade and complete the trade triangle that would ensure the economic prosperity of New Holland. In 1626, a Dutch expedition to take Elmina was almost wiped out in an ambush by the Portuguese, but in 1637, Elmina fell to the Dutch. In 1641 , the Dutch captured the island of Sao Tome and before the end of 1642, the rest of Portuguese Gold Coast followed. In August 1641 the Dutch formed a three-way alliance with the Kingdom of Kongo and Queen Nzinga of Ndongo, and with their assistance captured Luanda and Benguela, though without preventing the Portuguese from retreating inland into strongholds like Massangano, Ambaca and Muxima. With a steady source of slaves now secure, the Dutch abstained from further action, presuming that their allies would suffice against the Portuguese. Nonetheless, lacking artillery and firearms, Queen Nzinga and the Kongo proved unable to decisively defeat the Portuguese and their cannibalistic Imbangala allies.

Input: Still, the people of Liege refused to accept Burgundian rule. In October 1468, 240 rebels, under Jean de Wilde, Vincent de Bueren and Gosuin de Streel, invaded the city. In the confusion, Guy of Humbercourt and the entire Burgundian garrison fled. Liege was free again and Jean de Wilde occupied the Prince-Bishops' palace. One night, a Liege militia attacked Tongeren and killed all Burgundians there. After this, Jean de Wilde opened negotiations with Guy of Humbercourt. But Charles the Bold had other plans: he led an army towards Liege to deal once and for all with the rebellious city. He was accompanied by Louis XI of France. Several cities on their path were plundered, including Tongeren. On 22 October, a 500-strong militia that tried to stop the Burgundians at the village of Lantin were driven into the church and burned alive. Vincent de Bueren organised the defence of the city of Liege and achieved some successes with hit-and-run sorties. Jean de Wilde was mortally wounded during the raid of 26 October and died two days later. Best known is the attack by the six hundred Franchimontois in the night of 29-30 October, who sneaked out of the city and attacked the sleeping Burgundians, with the aim of killing the Duke and the King. The plan failed and all 600, including Vincent de Bueren and Gosuin de Streel, were killed. The next day, Liege surrendered, and at the command of Charles the Bold, hundreds of Liegois were tied together and thrown into the Meuse river. The city was set alight and is said to have burned for seven weeks.

Question: What date did Jean de Wilde die?

Input: Constantinople had been an imperial capital since its consecration in 330 under Roman Emperor, Constantine the Great. In the following eleven centuries, the city had been besieged many times but was captured only once: during the Fourth Crusade in 1204.:304 The crusaders established an unstable Latin state in and around Constantinople while the remaining empire splintered into a number of Byzantine successor states, notably Nicaea, Epirus and Trebizond. They fought as allies against the Latin establishments, but also fought among themselves for the Byzantine throne. The Nicaeans eventually reconquered Constantinople from the Latins in 1261. Thereafter, there was little peace for the much-weakened empire as it fended off successive attacks by the Latins, the Serbians, the Bulgarians, and, most importantly, the Ottoman Turks. The Black Plague between 1346 and 1349 killed almost half of the inhabitants of Constantinople. The city was severely depopulated due to the general economic and territorial decline of the empire, and by 1453 consisted of a series of walled villages separated by vast fields encircled by the fifth-century Theodosian walls. By 1450 the empire was exhausted and had shrunk to a few square miles outside the city of Constantinople itself, the Princes' Islands in the Sea of Marmara, and the Peloponnese with its cultural center at Mystras. The Empire of Trebizond, an independent successor state that formed in the aftermath of the Fourth Crusade, also survived on the coast of the Black Sea.

BIMC offered consultancy services in design, management and documentation to architectural and planning firms. In 1984, he moved to Los Angeles where he was involved in some architectural consultancy and research on Iranian and Persianate subjects. Borbor returned to Iran in 1991 and established the Research Institute and Library of Iranian Studies , a non-profit, non-political, private and independent institution dedicated to the promotion of research in the field of Iranian and Persianate studies with special emphasis on novel and creative research
