The Stuart kings, supposedly descended from Fleance, ending with James VI of Scotland and 1st of England, who was ruling when the play was written.
Banquo's heirs are prophesied to become kings. Macbeth tries to frustrate this by having Banquo and his child killed, but he fails because Fleance lives on to become the father of a line of kings
Macbeth is talking about the witches' prophecy to Banquo "Thou shalt get kings thou thou be none". From this Macbeth infers (although the witches did not actually say so) that his children would not be kings. Macbeth translates "thou shalt get kings" into Banquo being the father to "a line of kings". Well, the witches only said "kings"--they didn't say it was more than two. Then he imagines that none of his children would be kings with a couple of synechdoches: he describes the crown as fruitless (without children) and the sceptre as barren (incapable of having children) when it is the king, himself, which he imagines as fruitless and barren. I cannot hear the phrase "a fruitless crown" without imagining Carmen Miranda. Sorry if I have now put this image in your head.
A big effect
he felt disgusted by them and thought he needed them
Act I.7 line 35
The line of eight kings in Shakespeare's play "Macbeth" is said to descend from Banquo, who was a character in the play and a friend of Macbeth. Banquo is described as being the ancestor of Scottish kings in the play.
The line of kings shown to Macbeth in his vision are intended to imply that Banquo's descendants will not only be kings but will be kings for ever. Naturally this was a polite flattery to King James, who was supposedly one of them. Anyway, Macbeth gets the point, although why it should distress him as much as it does is puzzling.
The witches' predictions that he will be the father of a line of kings.

That the witches' prophecy of Banquo as the ancestor of a long line of kings is fulfilled despite his murder is the reason that the kings appear in Act 4 Scene 1 of the play "Macbeth."Specifically, the kings are conjured up by the witches when Macbeth (d. August 15, 1057) comes to visit in Act 4 Scene 1. In Act 1 Scene 3, the witches predict that Macbeth will become king and that his best friend Banquo will be the ancestor to kings though not a king himself. In Act 3 Scene 3, Macbeth arranges to have Banquo killed. Act 4 Scene 1 shows that Macbeth find success in killing Banquo, but not in stopping Banquo's royal line.
Macbeth is shown a line of kings, all of whom resemble Banquo. This vision represents the prophecy that Banquo's descendants will inherit the throne, indicating that Macbeth's reign will not be secure and will eventually be usurped by Banquo's line.

In the fourth vision, the Witches conjure a procession of eight kings, with the last king holding a mirror that reflects even more kings, symbolizing Banquo's royal descendants. This vision reinforces the prophecy that Banquo's line will be kings, adding to Macbeth's paranoia and fear of losing his throne.
Act I.7 line 35
To make sure that Banquo's son wont become king as the witches prediccted.
