The Gulf states did not appear on the map by accident. They took shape inside a system Britain built and managed for its own maritime interests: treaties, agreements, residencies and protection arrangements that decided who ruled, where lines fell and what could never be done without London's consent. The Making of Arabia follows that system state by state, through the British India Office records. Each piece is anchored to specific files and pages. Where Britain decided the outcome, we say so plainly. Where a ruler moved events, we give that its due. Nobody gets agency they didn't have, and the tensions stay open for the reader to carry. This series is for readers who want to understand how the Gulf's rulers, borders and alliances came to be, and why the record behind them still matters today.
