Why did it become possible to establish the sole power of Napoleon Bonaparte in France?

At this time, the French authorities were fragmented. Napoleon gained credibility with the army, thanks to his talent as a commander, which contributed to a significant increase in his candidacy. Also, Napoleon was supported by the Notables (members of the assembly for solving state and administrative issues). These were the main reasons why Napoleon was able to disperse the local parliament and become emperor in 1805.
