Imperialism vs. Nationalism: Two nineteenth century depictions of executions

The two paintings below are among the most well-known of the past two centuries.

Compare and contrast the historical events surrounding these two incidents, and each artist's depiction of the respective events. (I highly suggest you click on the links-- they are quite interesting).

The Third of May 1808 by Francisco Goya.

Historical context: Spielvogel pg. 558.

Here is a good, simple analysis of the painting. Here is a more scholarly view, from the Met.

The Execution of Emperor Maximilian by Edouard Manet.

Historical context of Napoleon III's "Mexican adventure": Spielvogel pg. 623.

Here is an excellent web site from the MoMA discussing the above painting and Manet's several versions.

Finally, here are some questions for comparison (click on the paintings for separate pages devoted to each).
