this era of history is a weak spot for me. i know a bit, but there might be/are holes in my knowledge.
from what i know,
augustus was only a leader due to julius and the work that julius put in (i'm of course simplifying here).
the family name caesar helped augustus out a lot as well,as far as gaining followers was concerned, the money that julius left behind, augustus used to buy mercenaries,etc....
that is basically all i remember about augustus.
julius is by far the greater historical figure:
-highly accomplished military mind
- inspired loyalty among his soldiers (some of the wars they fought took close to a decade and still his men stood by him)
-skilled writer; his work has survived to this day - coined the famous phrase 'veni,vidi,veci, for example
-hooked up with cleopatra
all i remember about julius without googling, i'm going with julius caesar.
please correct me if i'm wrong. i'm always willing to learn more.
