Here is a question about this article: For less than a year between 186263, Peruvian ships, engaged in what became to be called the "blackbirding" trade, combed the smaller islands of Polynesia from Easter Island in the eastern Pacific to Tuvalu and the southern atolls of the Gilbert Islands (now Kiribati), seeking recruits to fill the extreme labour shortage in Peru. While some islanders were voluntary recruits the "blackbirders" were notorious for enticing islanders on to ships with tricks, such as pretending to be Christian missionaries, as well as kidnapping islanders at gun point. The Rev. A. W. Murray, the earliest European missionary in Tuvalu, reported that in 1863 about 170 people were taken from Funafuti and about 250 were taken from Nukulaelae, as there were fewer than 100 of the 300 recorded in 1861 as living on Nukulaelae.
What is the answer to this question: When did Murray report people missing because of Blackbirders?

So... 1863

Here is a question about this article: While Mont Blanc was first climbed in 1786, most of the Alpine four-thousanders were climbed during the first half of the 19th century; the ascent of the Matterhorn in 1865 marked the end of the golden age of alpinism. Karl Blodig (18591956) was among the first to successfully climb all the major 4,000 m peaks. He completed his series of ascents in 1911.
What is the answer to this question: What did the ascent of the Matterhorn mark?

So... the end of the golden age of alpinism
