Java War

The Java War (also known as the "Diponegoro War") was fought in Java between 1825 and 1830. It started as a rebellion led by Prince Diponegoro after the Dutch decided to build a road across a piece of his property that contained his parents' tomb.

The troops of Prince Diponegoro were very successful in the beginning, controlling the middle of Java and besieging Yogyakarta. Furthermore, the Javanese population was supportive of Prince Diponegoro's cause, whereas the Dutch colonial authorities were initially very indecisive. As the Java war prolonged, Prince Diponegoro had difficulties in maintaining the numbers of his troops. Prince Diponegoro started a fierce guerrilla war and it was not until 1827 that the Dutch army gained the upper hand. The Dutch colonial army was able to fill its ranks with troops from Sulawesi, and later on from the Netherlands.

Mormonism in the 19th century

This is a chronology of Mormonism. In the late 1820s, founder Joseph Smith, founder of the Latter Day Saint movement, announced that an angel had given him a set of golden plates engraved with a chronicle of ancient American peoples, which he had a unique gift to translate. In 1830, he published the resulting narratives as the Book of Mormon and founded the Church of Christ in western New York, claiming it to be a restoration of early Christianity.

Moving the church to Kirtland, Ohio in 1831, Joseph Smith attracted hundreds of converts, who were called Latter Day Saints. He sent some to Jackson County, Missouri to establish a city of Zion. In 1833, Missouri settlers expelled the Saints from Zion, and Smith's paramilitary expedition to recover the land was unsuccessful. Fleeing an arrest warrant in the aftermath of a Kirtland financial crisis, Smith joined his remaining followers in Far West, Missouri, but tensions escalated into violent conflicts with the old Missouri settlers. Believing the Saints to be in insurrection, the Missouri governor ordered their expulsion from Missouri, and Smith was imprisoned on capital charges.
