input: In 1506, Charles inherited his father's Burgundian territories, most notably the Low Countries and Franche-Comte. Most of the holdings were fiefs of the German Kingdom (part of the Holy Roman Empire), except his birthplace of Flanders, which was still a French fief, a last remnant of what had been a powerful player in the Hundred Years' War. As he was a minor, his aunt Margaret of Austria (born as Archduchess of Austria and in both her marriages as the Dowager Princess of Asturias and Dowager Duchess of Savoy) acted as regent, as appointed by Emperor Maximilian until 1515. She soon found herself at war with France over the question of Charles' requirement to pay homage to the French king for Flanders, as his father had done. The outcome was that France relinquished its ancient claim on Flanders in 1528. From 1515 to 1523, Charles's government in the Netherlands also had to contend with the rebellion of Frisian peasants (led by Pier Gerlofs Donia and Wijard Jelckama). The rebels were initially successful but after a series of defeats, the remaining leaders were captured and decapitated in 1523. Charles extended the Burgundian territory with the annexation of Tournai, Artois, Utrecht, Groningen and Guelders. The Seventeen Provinces had been unified by Charles's Burgundian ancestors, but nominally were fiefs of either France or the Holy Roman Empire. In 1549, Charles issued a Pragmatic Sanction, declaring the Low Countries to be a unified entity of which his family would be the heirs. The Low Countries held an important place in the Empire. For Charles V personally they were his home, the region where he was born and spent his childhood. Because of trade and industry and the wealth of the region's cities, the Low Countries also represented an important income for the Imperial treasury. The Burgundian territories were generally loyal to Charles throughout his reign. The important city of Ghent rebelled in 1539 due to heavy tax payments demanded by Charles. The rebellion did not last long, however, as Charles's military response, with reinforcement from the Duke of Alba, was swift and humiliating to the rebels of Ghent.

Question: Zheng He (Chinese: Zheng He ; 1371-1433 or 1435) was a Chinese mariner, explorer, diplomat, fleet admiral, and court eunuch during China's early Ming dynasty. He was originally born as Ma He in a Muslim family, later adopted the conferred surname Zheng from Emperor Yongle. Zheng commanded expeditionary voyages to Southeast Asia, South Asia, Western Asia, and East Africa from 1405 to 1433. His larger ships stretched 120 meters or more in length.

In the decades after the last voyage, Imperial officials minimized the importance of Zheng He and his expeditions throughout the many regnal and dynastic histories they compiled. The information in the Yongle and Xuande Emperors' official annals was incomplete and even erroneous; other official publications omitted them completely. Although some have seen this as a conspiracy seeking to eliminate memories of the voyages, it is likely that the records were dispersed throughout several departments and the expeditions - unauthorized by (and in fact, counter to) the injunctions of the dynastic founder - presented a kind of embarrassment to the dynasty. State-sponsored Ming naval efforts declined dramatically after Zheng's voyages. Starting in the early 15th century, China experienced increasing pressure from the surviving Yuan Mongols from the north. The relocation of the capital north to Beijing exacerbated this threat dramatically. At considerable expense, China launched annual military expeditions from Beijing to weaken the Mongolians. The expenditures necessary for these land campaigns directly competed with the funds necessary to continue naval expeditions. Further, in 1449, Mongolian cavalry ambushed a land expedition personally led by the Zhengtong Emperor at Tumu Fortress, less than a day's march from the walls of the capital. The Mongolians wiped out the Chinese army and captured the emperor. This battle had two salient effects. First, it demonstrated the clear threat posed by the northern nomads. Second, the Mongols caused a political crisis in China when they released the emperor after his half-brother had already ascended and declared the new Jingtai era. Not until 1457 and the restoration of the former emperor did political stability return. Upon his return to power, China abandoned the strategy of annual land expeditions and instead embarked upon a massive and expensive expansion of the Great Wall of China. In this environment, funding for naval expeditions simply did not happen. However, missions from Southeast Asia continued to arrive for decades. Depending on local conditions, they could reach such frequency that the court found it necessary to restrict them: the History of Ming records imperial edicts forbidding Java, Champa, and Siam from sending their envoys more often than once every three years.
