World-Famous Micronation to Announce Five-Acre Expansion, Unveil Two New States During November 14 Jubilee The Republic of Slowjamastan is celebrating its fifth anniversary of independence with a historic announcement: the nation is expanding its territory by nearly 50 percent. On Saturday, November 14, from 1–3 PM, Slowjamastan will host its 5th Anniversary of Independence Jubilee, featuring the official announcement and ribbon-cutting ceremony for five newly acquired acres of land, one for each year of independence. The five additional acres, contiguous with the nation's existing 11-acre territory, bring Slowjamastan's total footprint to 16 acres. The public is invited to participate in the festivities, which include: • Historic ribbon-cutting celebrating Slowjamastan's territorial expansion. • Two new states officially commemorated within the nation. • Visa-free entry for the first 10,000 visitors. Crocs remain strictly prohibited. • Free Cactus Cooler while supplies last. • Meet and greet with The Sultan and the Chief of the Porder Batrol. "Five years. Five acres. Sixteen acres of freedom, questionable legislation, and absolutely no Crocs," said The Sultan. "Most countries celebrate anniversaries with cake. We bought more country." Founded in 2021, the Republic of Slowjamastan has attracted worldwide media attention for its unconventional approach to nation-building, complete with its own government, passports, border checkpoints, and national traditions.
