The Confederation of Murcia
الِاتِّحَاد مُرْسِيَة (Al-Ittiḥād Mursiya)
La Confederación de Murcia
The Confederation of Murcia was formed by the Cuyper Accords to help resolve the Tribulations [1] following the Republican Wars. Like most of the Mediterranean Republics it had a triune State Council acting as Head of State, although most of its powers were delegated to the First Secretary. This being because each State Councillor was themselves a Head of State: the Princes-General of the Aragonese Republic, the Ra's of the Republic of Granada, and the King of the Commonwealth [2]. Pragmatically these were typically the Medial Prince-General, a Wazir of Murcia, and a Lord Lieutenant of Murcia (usually also of the Balearic Protectorate).
The Accords also mandated rotating the First Secretariat among Gharbi Muslim, Papal Catholic, and Sephardic Jew, with Secretaries of Government having portfolios for each. Half the Members of the Assembly are also assigned to each religious denomination at each census (currently 43% Muslim, 42% Christian, 15% Jewish) though it's not always clear if the Member is an actual practitioner rather than nominal.
The Flag of the Confederation itself is a compromise based on the historical and neighbouring flags albeit the Commission headed by Lord Lieutenant Miles FitzGerald carried through aesthetic considerations [3]. Blue is for Aragon, Red for Granada, White for peace, 3 stripes for the 3 major religions, 2 stars for the main traditional divisions of the region.
[1] Think OTL Troubles crossed with the Yugoslav Wars
[2] England, Denmark, Ireland, the Netherlands, Wendland, and the Overseas Territories
[3] No damn maps on flags!
