According to a Wikipedia article, a war between the Portuguese rulers of Goa and the Maratha Empire in India occurred in mid-1640 to early 1641. The 4,500 account of the said war was supplied with various sources, including an alleged book entitled Mistrust Between States by an author named Mark Thompson. The book, as it turned out in the research of a skeptical Wikipedia user known as ShelfSkewed, did not exist. Recently, after further unearthing of facts, Wikipedia finally decided that the entire war didn’t exist either.
The entry, entitled the Bicholim Conflict, stayed in Wikipedia for 5 years, 5 months, and 25 days—all the while being false and non-existent in the records of history. It had even achieved a Good Article status and was nominated to be among one of the site’s daily Featured Articles. Both recognitions are typically rewarded to articles that are well-written and well-researched.
The writer of the article has not been determined yet, but Yahoo! News reports that members of the Wikipedia community have narrowed it down at least one suspect.
The Bicholim Conflict has been deleted from Wikipedia and now joins a long list of hoaxes that have been posted on the site.
