A weak alliance headed under the leadership of Vienna.
Step-by-step explanation:
The German confederation is an alliance among 39 states that speaks German, though excluding the Eastern portion under the kingdom of Prussia including East and west Prussia along with Posen. This confederation became weak after the rivalry between the kingdom of Prussia and the Austrian empire, amid difficulty among its members to compromise.
