context: The Reciprocal and Mutual Duty Betwixt a Free King and His Natural Subjects (original Scots title: The Trve Lawe of free Monarchies: Or, The Reciprock and Mvtvall Dvtie Betwixt a free King, and his naturall Subiectes) is a treatise or essay of political theory and kingship by James VI of Scotland (later to be crowned James I of England too). It is believed James VI wrote the tract to set forth his idea of kingship, in contrast to the contractarian views espoused by, among others, George Buchanan (in "De Jure Regni apud Scotos", 1579). James VI had the work published in 1598. It is considered remarkable for setting out the doctrine of the "divine right of kings" in Scotland, and latterly England, for the first time.

The document proposes an absolutist theory of monarchy, by which a king may impose new laws by royal prerogative but must also pay heed to tradition and to God, who would "stirre up such scourges as pleaseth him, for punishment of wicked kings". "Basilikon Doron", written as a book of instruction for the four-year-old Prince Henry, provides a more practical guide to kingship. Despite banalities and sanctimonious advice, the work is well written, perhaps the best example of James's prose. James's advice concerning parliaments, which he understood as merely the king's "head court", foreshadows his difficulties with the English Commons: "Hold no Parliaments," he tells Henry, "but for the necesitie of new Lawes, which would be but seldome".
