Input: Question: What year was the song that "Ishe Komborera Africa" was selected to replace written? Passage 1:Following Rhodesia's Unilateral Declaration of Independence from the British Empire, the new Rhodesian authorities started to crack down on African liberation movements. One of their considerations was to ban performance of "Ishe Komborera Africa" in African schools and public performance of it often made people liable for arrest by the British South African Police. The District Commissioner for Gutu abolished the Gutu African Council after its leader opened a meeting by singing "Ishe Komborera Africa" in the District Commissioner's presence. The Commissioner also had the leader arrested but he was released without charge. Following the Southern Rhodesian general election, 1980, after Zimbabwe Rhodesia returned to British control as Southern Rhodesia, Robert Mugabe's Zimbabwe African National Union party won to become the first government of an independent Zimbabwe. After this, "Ishe Komborera Africa" was selected to replace the official "God Save the Queen" of Southern Rhodesia and the unofficial "Rise, O Voices of Rhodesia" of Rhodesia as the national anthem of an independent Zimbabwe as it was a symbol of black African struggles and solidarity against apartheid systems in South Africa and Namibia. At the Zimbabwean independence ceremony, the Union Jack was lowered to "God Save the Queen" and the new flag of Zimbabwe was raised to "Ishe Komborera Africa" in Salisbury.
 Passage 2:Villa de San Agustin de Laredo was founded in 1755 by Don Tomas Sanchez while the area was part of a region called Nuevo Santander in the Spanish colony of New Spain. Villa de San Agustin de Laredo got its name from Laredo, Cantabria, Spain and in honor of Saint Augustine of Hippo. In 1840, Laredo was the capital of the independent Republic of the Rio Grande, set up in rebellion to the dictatorship of Antonio López de Santa Anna and brought back into Mexico by military force. In 1846, during the Mexican–American War the town was occupied by the Texas Rangers. After the war the Treaty of Guadalupe-Hidalgo ceded the land to the United States. A referendum was taken in the town, which voted overwhelmingly to petition the American military government in charge of the area to return the town to Mexico. However, this petition was rejected, and in response the bulk of the population moved over the river into Mexican territory to found the new town of Nuevo Laredo.
 Passage 3:The explorer-geographer David Thompson, working as head of the North West Company's Columbia Department, became the first European to explore the Inland Empire (now called the Inland Northwest). Crossing what is now the Canada–US border from British Columbia, Thompson wanted to expand the North West Company further south in search of furs. After establishing the Kullyspell House and Saleesh House trading posts in what are now Idaho and Montana, Thompson then attempted to expand further west. He sent out two trappers, Jacques Raphael Finlay and Finan McDonald, to construct a fur trading post on the Spokane River, which flows west from Lake Coeur d'Alene to the Columbia River, and trade with the local Indians. This post was established in 1810, at the confluence of the Little Spokane and Spokane rivers, becoming the first enduring European settlement of significance in what later became Washington state. Known as the Spokane House, or simply "Spokane", it was in operation from 1810 to 1826. Operations were run by the British North West Company and later the Hudson's Bay Company, and the post was the headquarters of the fur trade between the Rocky and Cascade mountains for 16 years. After the latter business absorbed the North West Company in 1821, the major operations at the Spokane House were eventually shifted north to Fort Colville, reducing the post's significance.
