The Time War.
There are male (the Doctor, the Master etc.) and female (Romana, the Rani, Susan etc.) timelords. It's pretty easy to figure out from there.
(Spoilers to come.) It's always been assumed that the only way for the Doctor to end the war was to destroy his people as well as the enemy, but at the end of season four more is revealed. As he explains in The End of Time, during the Time War the Time Lords were becoming too ruthless and too ambitious. A quote from The End of Time: Lord President: "We will ascend, to become creatures of consciousness alone. Free of these bodies, free of time, and cause and effect, while creation itself ceases to be." The Doctor: " You see now? That's what they were planning, in the final days of the war... I had to stop them." The Time Lords had been poisoned by war and ambition, and the Doctor had to stop them from going too far (as he began to do himself in The Waters of Mars) and becoming gods themselves, so he destroyed them and ended the Time War.
The Doctor is the last of the Timelords, from the long running BBC si-fi series "Doctor Who". The Timelords were a race from the planet Gallifrey. During the Last Great Time War, between the Daleks and the Timelords, The Daleks, Gallifrey and the rest of the Timelords were Destroyed. The Doctor was instrumental in the destruction thereby bringing the end of the War. The Doctor doesn't hate his planet, but has instead, been involved in a long debate with his people about the nature of the Timelord's place in the universe. This disagreement was the genesis for The Doctors travelling lifestyle. In 'The End of Time', we see scenes from the Time War, as the Time Lord president Rassilon prepares to shift Gallifrey itself out of the Time War, to modern day Earth. Here we learn that Time Lord society had become brutal and bloodthirsty over the course of the ceaseless war against the Daleks. Their own plan was 'the end of time itself', to destroy all of creation and for the Time Lords to ascend. This, the Doctor explained, is why he had to destroy his own people too, and never let them return.
The Toclafane's appearance is in the episodes The Sound of Drums and The Last of the Time Lords, the final two parts of the three-part season three finale in New Who.
River Song is an older version of Amy and Rory's daughter (Melody Pond) and probable love interest of the Doctor. Having been conceived in the TARDIS (the Doctor's time machine), Melody Pond/River Song received a very high exposure to the time vortex, resulting in her DNA being partly similar to that of the Time Lords. This means that River has the ability to regenerate, although she used up the rest of her regenerations to save the Doctor.
The episode before 'Last Of The Time Lords' is 'The Sound Of Drums'.
Because the astronaut shot him whilst he was regenerating. A Time Lord can be killed out right if they are between regenerations. This shows us that even Time Lords are not invincible.
He 'borrowed' it from the Time Lords. Originally, Time Lords did not interfere with other goings-on around the universe, but sat and watched, unless something needed to be done, in which case they got the Doctor to do the dirty work. They lent him the TARDIS to use to do so in. However, all of the Time Lords but the Doctor and the Master were killed along with their home planet Gallifrey, in the deadly Time War against the evil Daleks. The Doctor was devastated by the consequences of the war, but kept the TARDIS to hop around time and space and carry on righting wrongs.
Doctor Who has two hearts (harts refers to deer, Doctor Who has no deer)- it is a characteristic of Time Lords.
I believe he is the same age as The Doctor, before he rapidly aged The Doctor in "The Last of the Time Lords."
The real name of the Time Lords, including the Doctor, has never been revealed in the "Doctor Who" series. It is a mystery that has been intentionally left unanswered by the show's writers.
The Time Lords have returned in different Doctor Who episodes for various reasons, such as to warn or aid the Doctor or to address threats to the universe. Their return often signifies a significant storyline or event in the Doctor Who universe.
The battle with daleks and all time lords.
I can't speak for the classic series, but in New Who, the Master is shot by Lucy Saxon (his wife) and refuses to regenerate in Last of the Time Lords. However, at the very end of the episode, a woman is seen picking up his signet ring from the ashes of his funeral pyre. In End of Time, the Master is resurrected. He attacks the Time Lord President at the end of the episode and disappears with the rest of the Time Lords.
not many people know if they are real or not but they can be around now like the doctor.
He is a Gallifreyan from the planet Gallifrey. The Gallifreyans are also known as Time Lords.
The Master was the only other Time lord left apart from the Doctor. His death made the Doctor the only time load left alive
