The 4th kingdom in Daniel 2 & 7 is Pagan Rome.
the beasts in Revelation 13 are in the opposite order to Daniel 7
Daniel has the order of:-
1) Lion
2) Bear
3) Leopard
4) Dragon
4The first was like a lion
5And behold another beast, a second, like to a bear
6After this I beheld, and lo another, like a leopard,
7After this I saw in [the night ]visions, and behold a fourth beast, dreadful and terrible, and strong exceedingly;
and it had great iron teeth: it devoured and brake in pieces, and stamped the residue with the feet of it:
and it was diverse from all the beasts that were before it; and it had ten horns.
Revelation 13:1
1) Dragon
2) Leopard
3) Bear
4) Lion
And [the beast] which I saw was[ like] unto a leopard,
and his feet were as the feet of a bear,
and his mouth as the mouth of a lion:
John, in Revelation 13, sees, not four beasts, but one beast. Not a leopard, but like a leopard
—possessing all its cunning, cruelty and speed. But it also possessed
the dominant characteristics of the two other most powerful beasts
the royal splendor and kingly power symbolized by the mouth of the lion (Babylon);
the ponderous strength symbolized by the feet of the bear (Medo-Persia);
and the speed, cunning and cruelty of the leopard (Greece)
