Parties and factions in Isabelline Spain

There were numerous political parties and factions in Isabelline Spain (Spain during the reign of Isabella II, who reigned 29 September 1833 – 30 September 1868). Some of them are known by multiple names, and in many cases the lines between these were fluid over time, both in terms of individuals moving from one party or faction to another and in terms of parties or factions changing their stances. Many of these factions are subgroups of parties, and groupings sometimes overlapped. Many factions (especially within the Moderate Party) were based on little more than political clientelism.^[1]
