Current president, Florentino Perez was elected for his first term in 2000, based on his campaign to buy the world's best players.
His first signing was Luis Figo from arch-rivals FC Barcelona for a world-record fee of €60 million, with an overall spending of €119.25 million in Perez's first transfer window.
The next season, Real broke its own world-record and bought Zinedine Zidane for €73.50 million.
Even though his new Galacticos side won the Champions League in 2002, Perez continued his money-spending campaign by buying Ronaldo de Lima for €45 million and David Beckham for €37.5 million in the following two seasons.
However, following the initial success on the field and increased financial success through marketing revenue around the world, Real stopped winning titles and Perez resigned in 2006.
Los Blancos, however, continued their spending and splashed out €304 million in the three years without Perez.
The 68-year-old returned for his second term in 2009 and immediately spent €257.4 million in the 2009/10 window, once again breaking the world record fee by signing Cristiano Ronaldo for €94 million.
There was also Kaka for €65 million, Xabi Alonso for €35.4 million and Karim Benzema for €35 million, as well as a few minor signings - completing the most expensive transfer window in history.
Three yes of lesser spending saw the signings of Angel Di Maria for €33 million, as well as Fabio Coentrao and Luka Modric for €30 million apiece. There was then another major cash injection in 2013/14 and this season.
Gareth Bale, who arrived for €94 million, is Perez's latest signing to break the world record, while James Rodriguez arrived for €80 million.
