i know what it means! (although i just started the 6th grade a month ago) :]

it means-

King George has caused the rebellion in the midst of the colonist

In the Declaration of Independence he stated: "He has excited domestic insurrections amongst us, and had endeavored to bring on the inhabitants of our frontiers the merciless Indian Savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes, and conditions."

Dictatorship and oppressing the free Confederate States of America

No, the phrase "jealousies will be always arising insurrections will be constantly happening" does not represent an ethos. An ethos is a fundamental character or spirit of a culture or community, while this phrase describes ongoing negative behaviors.
