Frugalware was founded in 2004 by Miklós Vajna. He considered Slackware's package manager pkgtools too slow, and wanted to rewrite it in C.
He was told that it would never be accepted by Slackware, so Vajna started to think about founding a separate Linux distribution.
He replaced Slackware's original package manager, init scripts and build system. As a result, Frugalware was born.
