"ISIL began in 1980 as Libertarian International, founded by Canadian libertarian activist and publisher Vince Miller. LI started the international libertarian conferences in Zurich, Switzerland in 1982. The current ISIL was formed in 1989 through the merger of LI with the Society for Individual Liberty, the first explicitly libertarian grassroots organization which had been founded by Jarret Wollstein, Dave Walter and Don Ernsberger in 1969."
