The World Rally Championship (WRC) is a rallying series administrated by Fédération Internationale de l'Automobile (FIA), motorsport's world governing body. The series currently consists of 13 three-day events driven on surfaces that range from gravel and tarmac to snow and ice. Each rally is split into 15–25 special stages, which are run against the clock on closed roads. The WRC was formed from well-known and popular international rallies, most of which had previously been part of the European Rally Championship and/or the International Championship for Manufacturers; the series was first contested in 1973. The drivers' championship was first awarded in 1977 and 1978 as an FIA Cup for Drivers title, to Sandro Munari and Markku Alén, respectively. The first official world champion in rallying was Björn Waldegård in 1979.
Each season normally consists of 12 to 16 rallies driven on surfaces ranging from gravel and tarmac to snow and ice. Points from these events are calculated towards the drivers', co-drivers' and manufacturers' world championships. The driver's championship and manufacturer's championship are separate championships, but are based on the same point system. In the current points system, points are awarded at the end of each rally to the top ten WRC (overall) drivers that qualify as follows: 25, 18, 15, 12, 10, 8, 6, 4, 2, 1. In addition to those points, from 2011 each event holds 1 special stage, the Power Stage, in which drivers and co-drivers can score extra points – currently awarded to five fastest drivers (5, 4, 3, 2, 1). 
Sébastien Loeb holds the record for the most drivers' championships, winning nine during his career. He also holds the record for the most championships won in a row; he won nine consecutive titles from 2004 to 2012. Sébastien Ogier is second with six championships won consecutively from 2013 to 2018. France have won the most titles with 16 championships between 3 drivers. Finland are second with 14 championships between 7 different drivers. Citroën cars have won the most drivers' championships with nine titles, all of them with Loeb.
