The hereditary rank or title of baronet, or the domain and property controlled by a baronet.
From baronet (itself a diminutive of baron, created 1611 by King James I) + -cy suffix meaning 'state or rank.' The term is distinctly British, marking a specific rank between common gentry and true nobility.
King James I invented baronetcies as a fundraising scheme—he created new titles and sold them to wealthy merchants who wanted status; it was basically medieval monetization, and it worked so well that the practice continued and baronets became a recognized part of British society.
