Continental congress
By the South, I assume you are referring to the American Civil War. The South was trying to get support from Europe (such as the UK for example) to aid them in the war. However, Europe never got involved in the American Civil War.
There were only two ways that the South could have won the Civil War. With British aid - not possible after Lincoln issued the Proclamation. Or if Lincoln had been voted out in November 1864 - he wasn't.
Both sides in the Spanish Civil War received aid from outside Spain. France did not receive aid during or as a result of the Spanish Civil War.
If you are refering to the American Civil War, niether had support from European countries. The South wanted the aid of the British, and tried many times to break the North's naval blockade. The South depreately needed the aid of Britain, not militarily, but finacialy. The South needed some place to sell the cotton they grew, since they were unable to do so they suffered from 7000% inflation at the end of the war. One could write a whole masters thesis on Europes effects on the Civil War.

In the civil war black people aided the cause by escaping from the south and fighting in the north causing a drastic change in numbers and ability to win. With the black leaving, the south was also dreadfully out of economy since most of their income was from black slaves.
The South hoped to receive aid from England during the Civil War primarily due to England's reliance on Southern cotton for its textile industry. The South believed that the economic impact of a cotton shortage would compel England to intervene on their behalf. Additionally, there were cultural and historical ties between the South and England that the Confederacy hoped to leverage in gaining support. However, despite these hopes, England ultimately chose to remain neutral in the conflict.
The fighting quality of their manpower. A clear mission to defend the homeland. Sympathy - and possible aid - from Britain and France.
