Please accept my warmest thanks for your kind invitation to the 
Second Party Congress of the Austrian Social Democrats, and at 
the same time my regret that I shall not be able to attend in 
person; my best wishes for the successful course of your 
deliberations. 

Since Hainfeld,’*' when the Austrian workers’ party found its 
feet again, you have made enormous progress. This is the best 
guarantee that your present Congress will be the starting point for 
new and even more important victories. 

The invincible inner strength possessed by our party is proved 
not only by its successes following swiftly one upon another, not 
only by the fact that it, as last year in Germany, has this year 
overcome the state of emergency in Austria.’ It shows its 
strength far more by conquering obstacles in all countries, and 
accomplishing things where the other parties, recruited from the 
propertied classes, come helplessly to a halt. While the propertied 
classes of France and Germany feud with irreconcilable hatred, 
French and German proletarians work hand in hand. And while, 
around you in Austria, the propertied classes of the various crown 
lands lose the last remnants of the ability to rule in their blind 
national discord, your Second Party Congress will display the 
picture of an Austria which no longer knows national discord— 
the Austria of the workers.
