When it comes to expressing a connection between two parties, sometimes the phrase "was allied to" might feel repetitive or overused. Fortunately, there are plenty of synonyms and alternative phrases that convey the same meaning while adding some variety to your writing. For example, you could say that two parties were "joined forces," "aligned in purpose," "united in pursuit," or "linked together." Other options might include phrases like "stood hand in hand," "worked in tandem," or "shared a common goal." No matter which synonym you choose, the key is to find a phrase that accurately reflects the nature of the connection between the two parties and fits smoothly into your writing.
