The Royal Bank of Scotland received its royal charter on 31 May 1727, the second bank to be established in Scotland after the Bank of Scotland (1695). The charter, granted by King George I under the patronage of Archibald Campbell, Earl of Ilay (later 3rd Duke of Argyll), was a direct response to the Darien Scheme disaster of the 1690s — a failed Scottish colonial venture that cost the kingdom a quarter of its liquid wealth and became a catalyst for the 1707 Act of Union with England. The new bank's initial capitalization was $254,000 divided into $127 shares subscribed by Scottish merchants and landowners. The Earl of Ilay served as the first governor from 1727 to 1737, providing political protection that allowed the bank to survive the competitive discounting wars with the Bank of Scotland in the 1730s. The Royal Bank's first innovation came in 1728, when it granted the world's first overdraft — $1,270 to Edinburgh merchant William Hog — creating a cash credit facility that would become the foundation of modern retail banking. The bank began issuing its own promissory notes in 1727, establishing a correspondent network that included an account with the Bank of England in 1728. For the first 56 years, the bank operated solely from its Edinburgh head office, opening its first branch in Glasgow in 1783. The 19th century brought expansion through acquisition: the Commercial Bank of Scotland (1810), the National Bank of Scotland (1825), and numerous regional banks. By 1914, the Royal Bank had 162 branches and 900 staff, though it remained primarily a Scottish institution with no branches south of the border except a London office. The interwar period marked the first English expansion: Drummonds Bank in London (1924), Williams Deacon's Bank in Manchester (1930), and Glyn, Mills & Co. (1939). These acquisitions provided footholds in high-net-worth banking and northern England commercial lending. The 1969 merger with the National Commercial Bank of Scotland created the National & Commercial Banking Group with 682 branches. In 1985, the English subsidiary Williams & Glyn's Bank was fully merged under the Royal Bank name, creating Britain's first truly nationwide high street bank. The international expansion began in 1988 with the $440 million acquisition of a majority stake in Citizens Financial Group, a US regional bank. The 1990s brought further US growth and the 1993 acquisition of Edinburgh private bank Adam & Company. The transformative moment came in 2000, when Royal Bank of Scotland outbid Bank of Scotland to acquire National Westminster Bank (NatWest) for $26.7 billion in a hostile takeover — the largest in British banking history. The deal quadrupled RBS's asset base to over $635.0 billion and added approximately 3,000 branches, Ulster Bank in Northern Ireland, and Coutts & Co. Fred Goodwin, who became group CEO in 2001, pursued aggressive expansion including the 2004 $7.4 billion acquisition of Charter One Financial in the US. The 2007 consortium acquisition of ABN AMRO for $78.5 billion, led by RBS with Fortis and Santander, proved catastrophic: the assets were acquired at the peak of the market, and within months the global financial crisis exposed the group's excessive leverage and poor risk management.
