 The cemetery was founded in 1848 and was for twenty years the main general cemetery for Sydney, with the total number of burials being about 18,000.
 Many people who were important to the early history of colonial Australia are buried there.
 It is the only one of Sydney's three main early cemeteries that still exists.
Mormonism and Mormon adherents have been subjected to, as well as in a few instances themselves used, significant violence throughout much of the religion's history.
 In the early history of the United States, violence was used as a form of control.
 Many people of different faiths used violence in order to harass and persecute people who adhered to different religious beliefs.
 The members of the Church of Jesus Christ of Latter Day Saints, especially in its early history, were both the victims and sometimes the perpetrators of violence in much the same way as were the followers of other major religions. Mormons were violently persecuted and pushed from Ohio to Missouri, from Missouri to Illinois and from Illinois, they were pushed west to the Utah Territory.
 There were incidents of massacre, home burning and pillaging, followed by the murder of their founder, Joseph Smith.
 However, there were also a few notable incidents in which Latter-day Saints perpetrated violence, such as the Mountain Meadows massacre.
The 2002 Poso bus attacks were a series of terrorist attacks targeting public transport that occurred in Central Sulawesi, Indonesia, between 5 June and 8 August 2002.
 In total 7 people were killed and 26 wounded, including an Italian tourist.
 The first attack occurred on 5 June 2002, when a bomb detonated in an "Antariksa"-owned public bus servicing the Palu, Poso and Tentena routes.
 Four passengers were killed instantly and 17 more were wounded, one of who would succumb to his injuries two weeks later.
 On 13 July 2002 the second attack occurred on the trans-Sulawesi highway when the bus driver found a bag lying on the road and asked his conductor to retrieve it, triggering the device: an 18-year-old bystander was killed and at least 4 others severely wounded in the blast.
 In the third attack, on 8 August 2002, an Italian tourist was killed and at least 4 Indonesians injured when unknown assailants fired automatic weapons into another bus.
The May 2004 Caribbean floods were a flood event that took place in the Caribbean Islands, mainly Hispaniola and some parts of Northern Puerto Rico from May 18, 2004 to May 25, 2004.
The storm caused significant rainfall, with over 9.7 inches of rain falling at the most in Haiti, and 10 inches falling at the most in the Dominican Republic.
 These floods were caused by over two weeks of persistent rain in the Caribbean area, which eventually caused the landslides that killed many people.
 The floods caused much damage in Haiti and the Dominican Republic, with over 1,300 homes being destroyed and about 2,000 people being killed.Due to this destruction, nearly 15,000 people were displaced with nowhere to live.
 The area that felt the worst of the flooding was the town of Jimani, near the border of Haiti and the Dominican Republic.In fact, the destruction present at Jimani was so bad that Dominican president Hipolito Mejia declared a national day of mourning after seeing the effects of the storm.
The Milltown Cemetery attack (also known as the Milltown Cemetery killings or Milltown Massacre) took place on 16 March 1988 in Belfast's Milltown Cemetery.
 During the funeral of three Provisional IRA volunteers killed in Gibraltar, an Ulster Defence Association (UDA) volunteer, Michael Stone, attacked the mourners with hand grenades and pistols.
 As Stone then ran towards the nearby motorway, a large crowd began chasing him and he continued shooting and throwing grenades.
 Some of them caught him and began beating him, but he was rescued by the police and arrested.
 Three people had been killed and more than 60 wounded.
 The "unprecedented, one-man attack" was filmed by television news crews and caused shock around the world.
The Trafalgar Cemetery is a cemetery in the British Overseas Territory of Gibraltar.
 Formerly known as the Southport Ditch Cemetery, it occupies a small area of land just to the south of the city walls, in what had been a defensive ditch during the period of Spanish rule of Gibraltar.
 Although it is named for the Battle of Trafalgar of 21 October 1805, only two victims of the battle are buried there.
 The remainder of the interments are mostly of those killed in other sea battles or casualties of the yellow fever epidemics that swept Gibraltar between 1804 and 1814.
 In addition, tombstones were transferred to the Trafalgar Cemetery from St. Jago's Cemetery and Alameda Gardens.
Operation Flavius (also referred to as the "Gibraltar killings") was a controversial military operation in which three members of the Provisional Irish Republican Army (IRA) were shot dead by the British Special Air Service (SAS) in Gibraltar on 6 March 1988.
 The three—Seán Savage, Daniel McCann, and Mairéad Farrell—were believed to be mounting a bombing attack on British military personnel in Gibraltar.
 Plain-clothed SAS soldiers approached them in the forecourt of a petrol station, then opened fire, killing them.
 All three were found to be unarmed, and no bomb was discovered in Savage's car, leading to accusations that the British government had conspired to murder them.
 An inquest in Gibraltar ruled that the SAS had acted lawfully, while the European Court of Human Rights held that, although there had been no conspiracy, the planning and control of the operation was so flawed as to make the use of lethal force almost inevitable.
 The deaths were the first in a chain of violent events in a fourteen-day period; they were followed by the Milltown Cemetery attack and the corporals killings in Belfast.
The process of assembling the International Space Station (ISS) has been under way since the 1990s. "
Zarya", the first ISS module, was launched by a Proton rocket on 20 November 1998.
 The STS-88 shuttle mission followed two weeks after "Zarya" was launched, bringing "Unity", the first of three node modules, and connecting it to "Zarya".
 This bare 2-module core of the ISS remained unmanned for the next one and a half years, until in July 2000 the Russian module "Zvezda" was added, allowing a maximum crew of two astronauts or cosmonauts to be on the ISS permanently.
