In politics, a boss is a person who controls a faction or local branch of a political party. They do not necessarily hold public office themselves; most historical bosses did not, at least during the times of their greatest influence. Numerous officeholders in that unit are subordinate to the single boss in party affairs. Bosses may base their power on the support of numerous voters, usually organized voting blocs, and manage a coalition of these blocs and various other stakeholders. When the party wins, they typically control appointments in their unit, and have a voice at the higher levels.

A cacique, sometimes spelled as cazique was a tribal chieftain of the Taíno people, who were the indigenous inhabitants of the Bahamas, the Greater Antilles, and the northern Lesser Antilles at the time of European contact with those places. The term is a Spanish transliteration of the Taíno word kasike.
