Polygamy and polyamory may sound similar, but they most certainly do differ. Whether you’re currently navigating your own sexuality or you’re just satisfying your curious mind, understanding the differences between these two relationship structures is important.
The main differences between polygamy and polyamory are the legalities of the relationship and the fact one involves marriage while the other is more flexible.
However, there are other key differences that may surprise you, like the emotional ins-and-outs of each, how they handle communication and even the level of commitment involved.
At a glance, here are the main differences between polygamy and polyamory:
| Polygamy | Polyamory |
|---|---|
| A marriage system where individuals have multiple spouses simultaneously. | The practice of having multiple romantic or sexual partners with the knowledge and consent of all involved. |
| Legal in some countries and cultures, often with specific regulations and hierarchies. | Generally not legally recognised as a marriage, but rather a consensual relationship structure. |
| Primarily on marriage and family structure. | Emphasises emotional, romantic, and sexual connections with multiple partners. |
| Often involves a hierarchical structure, with one spouse considered primary. | Typically non-hierarchical, with all partners considered equal. |
| Less socially accepted in many Western cultures, often associated with religious or cultural traditions. | Increasingly gaining social acceptance, particularly in Western countries. |
Let’s dive in and explore these two relationship structures to gain a deeper understanding of what sets them apart.

What is Polyamory?
| Polyamory is the practice of engaging in multiple romantic or sexual relationships simultaneously, with the full consent and knowledge of everyone involved. |
Unlike traditional monogamous relationships, types of polyamory do not adhere to the idea of exclusivity and instead allow individuals to form deep emotional connections with more than one person.
Polyamory is not solely about physical intimacy but rather emphasises the importance of developing and maintaining meaningful relationships with multiple partners.
It is often seen as a way to challenge societal norms and expectations surrounding love, relationships, and marriage.
| Polyamory is an umbrella term that covers relationships such as: • Ambiamorous relationships • Non-hierarchical polyamorous relationships • Open marriages • Poly-mono relationships • Kitchen table polyamorous relationships |
What is Polygamy?
| Polygamy is a marriage system where an individual has more than one spouse at the same time. Polygamous relationships are often culturally or religiously sanctioned and remains legal in certain countries and regions. |
Unlike polyamory, which focuses on consensual romantic and sexual relationships, polygamy typically places a greater emphasis on the family unit and marital structure.
Marriage relationships in polygamous arrangements often include established hierarchies, with one spouse recognised as primary.
While polygamy is rooted in cultural traditions and varies across different societies, its legality and social acceptance vary widely, often facing restrictions or stigma in Western cultures.
What is the Difference Between Polyamory vs Polygamy?
So, what is the difference between polygamy and polyamory? Well, Polyamory and polygamy both involve having relationships with multiple people, but they’re quite different. We’ve broken down the key differences between them
1. The Legalities
Polygamy is about being legally married to more than one person at the same time. The act of legally marrying more than one person is legal in some parts of the world, including Africa, Asia and the Middle East.
However, polygamy is not a legally recognised form of marriage in the UK and does not involve any legal documents beyond the first marriage.
Polyamory, on the other hand, doesn’t involve marriage as part of the structure, opting for more malleable, equal partnerships between everyone involved, which is legal as long as all relationships are consensual.
2. The Structure
Polygamy usually comes with a set structure, where one spouse might have a primary role, and it’s often linked to cultural or religious traditions.
On the flip side, polyamory is all about having multiple romantic or sexual partners with everyone’s consent and knowledge – no need for marriage here.
It focuses on equality among partners and building emotional and romantic connections without any set hierarchy, which is why it’s growing more popular among Brits. It’s more about personal freedom and is becoming increasingly accepted, especially in the West.
3. The Emotional Involvement
The way emotions play out in polyamorous and polygamous relationships can be quite different because of their core principles and the society around them.
In polyamory, emotional connections take centre stage. It’s all about having deep, meaningful connections with each partner.
This type of relationship thrives on open communication and emotional transparency, leading to a richer understanding and intimacy. There are no strict hierarchies here—every relationship is seen as equally important.
On the flip side, polygamous relationships might put less focus on emotions and more on family structure and social obligations, often linked to cultural or religious practices.
Emotional bonds are definitely there, but they might take a backseat to roles and responsibilities within the marriage. There’s usually a hierarchy, with one spouse being primary, which can cause uneven emotional connections.
So, while both relationship types allow for emotional attachments, how these emotions are expressed and valued can be quite different.
4. Communication
Communication is vital in both polyamory and polygamy, though it functions differently in each.
In polyamory, open and honest dialogue fosters trust and ensures that all partners’ needs and boundaries are respected, promoting emotional transparency and harmony. Each relationship is valued equally, necessitating ongoing communication.
Conversely, in polygamy, communication often revolves around maintaining family structure and fulfilling roles and responsibilities. Hierarchies may affect dialogue, with the primary spouse typically having more influence in decision-making.
While both require communication, polyamory prioritises emotional connections, whereas polygamy emphasises order and tradition.
5. Hierarchy & Equality
Polygamous marriages often involve hierarchies, with one spouse being considered primary or having more rights and privileges than others. This is in contrast to polyamory, where all involved parties are deemed equal.
While both types of relationships require open communication and trust, polyamory places a stronger emphasis on equality and non-hierarchical structures.Partners in polyamorous relationships often strive for open communication and fairness in their interactions with each other, while those in polygamous marriages may have limited decision-making power or agency within the relationship.
Technically speaking, no one can enter a polygamist relationship because it is against the law. Even the Mormon church, which is often thought of as allowing it, has actually ruled that they no longer condone it (as you may know if you watched the TV show, Big Love).
Anyone can enter into a polyamorous relationship. There are no rules about gender or sexual orientation.
The idea is that you are open to loving more than one person at once, regardless of how they identify. But it needs to be a conscious choice that everyone involved is aware of and has agreed to. Whether that’s a purely sexual or romantic relationships, or even a mix of both, it is completely up to the partners involved.
Is Polygamy a Type of Polyamorous Relationship?
While polygamy and polyamory both involve relationships with multiple people, polygamy is not considered a polyamory relationship.
The key distinction lies in the structure and intent of these relationships.
- Polygamy is a marriage-based system where an individual marries multiple spouses, often with a hierarchy and legal recognition in some cultures.
- Polyamory, on the other hand, is a more fluid, consensual relationship structure that is not centred around marriage but rather the desire to have emotional or romantic connections with multiple partners.
So, while they share some surface similarities, the underlying principles and configurations set them apart significantly.
What is the Difference Between Polygamy & Polyandry?
Polygamy is an umbrella term that refers to a marriage system where an individual has more than one spouse simultaneously. It encompasses more specific practices, such as polygyny and polyandry.
- Polygyny refers to a man having multiple wives, whereas polyandry describes a woman having multiple husbands.
- Polyandry is far less common globally compared to polygyny and often occurs in specific cultural or societal contexts where factors like population dynamics or economic considerations come into play.
Both systems fall under the wider concept of polygamy, but they differ primarily in the gender roles and family structures they create.
Who Can Enter a Polyamorous or Polygamist Relationship?
If you’re interested in polyamorous relationships and ready to be honest and consensual with multiple partners, you’re good to go!
The key is open communication, mutual respect, and being willing to handle any complex emotions that might come up. It’s also super important for everyone involved to fully understand and agree on how the relationship is structured.
On the other hand, entering a polygamist relationship often depends on cultural, religious, or legal allowances within certain countries and societies.It usually involves formal marital ties with multiple spouses and may require adherence to specific customs or traditions. If you’re interested in polygamy, you should be aware of the legal and societal contexts that may impact these relationships.
Summary: Demystifying Polyamory & Polygamy
So, to sum it all up, polyamory and polygamy both do refer to having multiple partners at the same time, but the way in which these relationships are carried out do differ.
- Polyamory = Consensual, non-monogamous relationships with emotional and often sexual intimacy with multiple partners.
- Polygamy = Marital relationships in which one person has multiple spouses, usually following specific cultural or religious customs.
