From Freeciv
Copying from Wikipedia to this wiki is not permissible because it uses a different license from Freeciv. Please avoid this.
Copying from Wikipedia to a Wikia wiki is permissible if both use the same license. It is necessary to include the proper acknowledgement so that readers can refer to the original and discover its authors.
One way to add attribution is to use the {{Wikipedia}} template. If your wiki does not have a copy of this template, you can find one here. Another option, often used by Wikipedians when using works from Wikia, is to make the attribution in the page history via the edit summary.
Wikia sites are not intended to duplicate substantial portions of Wikipedia or any other site. You may copy all or part of an article (and its links and templates) to start off a page on the subject, but you are expected to adapt it so as to reflect this particular wiki's slant on the subject.
