Grundaren av Targeryen-dynastin, Aegon Conqueror.För honom var Westeros styrd av kungar, inte herrar. Han hade också 3 drakar som Daenerys. Han erövrade alla kungarierna i Westeros (minus Dorne) och gjorde sig till kung av hela kontinenten.
Från sin wikisida (om du inte vet mycket om honom):
Aegon I Targaryen, known as Aegon the Conqueror, is an unseen character in Game of Thrones. He died almost three hundred years before the time of the series, and is not expected to appear. Aegon I Targaryen conquered all of Westeros (with the exception of Dorne) with three great dragons, Balerion, Vhagar and Meraxes, and unified the realm under his rule, founding the Targaryen dynasty. He was married to both of his sisters, Visenya and Rhaenys. He is a direct ancestor of Daenerys Targaryen.
EDIT (som svar på OP-kommentar):
After the Conquest, Aegon ruled for thirty more years, apparently wisely and well.
En annan passage:
He also knew that conquering Westeros had been the easy part and that the hard part would be maintaining the realm he had built. To ensure that his dream would not die, Aegon spent most of his time traveling the various Kingdoms on royal progresses to remind lords and smallfolk who ruled them and to make his presence familiar to them. He also refrained from trying to unite the Kingdoms under the same laws, instead allowing them to retain their old laws and he would judge crimes committed in these Kingdoms according to their customs.
Det fortsätter om och om om honom. Han var bara regerande missyr, var snäll mot den besegrade, inte verkställde sina lagar på den erövrade, var vänlig mot de sju troen (även när det inte var hans religion) etc. Så om något Dany är väldigt mycket som hennes förfader i många avseenden.
