The Latin name ''Confoederatio Helvetica'' was neologized and introduced gradually after the formation of the federal state in 1848, harking back to the Napoleonic Helvetic Republic, appearing on coins from 1879, inscribed on the Federal Palace in 1902 and after 1948 used in the official seal (e.g., the ISO banking code "CHF" for the Swiss franc, and the country top-level domain ".ch", are both taken from the state's Latin name). ''Helvetica'' is derived from the ''Helvetii'', a Gaulish tribe living on the Swiss plateau before the Roman era.
